2016 Postmortem
Related: About this forumPolls are beginning to turn Hillary's way.
This is from Huffington's Pollster range 8/1 to current.. with less smoothing option.

Looks like Bernie is flatlining while Hillary is starting to move back up slightly. I suspect this is the result of many voters coming to realize the email "scandal" is not actually a scandal.

(5,204 posts)Here are the polls from 2007-2008. You can see a substantial improvement for Hillary in September and the first half of October 2007.

That's ancient history dude and as far as I know there is no candidate Obama anywhere in sight.

(11,366 posts)The OP's chart looks like it's leaving out a lot of polls.
Here's what I get July-Sept including all the polls:

DCBob
(24,689 posts)I simply did a range from 8/1 to current and selected less smoothing option as I indicated in the OP.
DCBob
(24,689 posts)Persondem
(2,101 posts)Seems like including him clouds the true picture .... though I could see if every so often a pollster included him as a possibility.
DCBob
(24,689 posts)No doubt Hillary's numbers would go up.
jfern
(5,204 posts)No tweaking was done. And you can see that most of Q3 as well as early October 2007 were great for her and bad for Obama.

DCBob
(24,689 posts)DCBob
(24,689 posts)Barack Obama was probably the most inspiring candidate to run for President in 5 decades and his campaign was probably most brilliant and effective in history.
Bernie does not compare in any way shape or form.
jfern
(5,204 posts)DCBob
(24,689 posts)and Bernie is quite uninspiring to many.
jfern
(5,204 posts)That doesn't happen to inspiring people.
DCBob
(24,689 posts)jfern
(5,204 posts)Also the MOE is 4.9%, so Sanders' lead is probably closer to what the other polls have shown.
DemocratSinceBirth
(101,852 posts)BTW, if you look at the internals she is already leading among Dems in the last two polls...
I know it's a open primary but if Trump is still viable Indys will vote for him and to stop him.
jfern
(5,204 posts)And a drop of 3 points between 2 polls that have MOE of 5 is completely statistically insignificant.
DCBob
(24,689 posts)The 5 previous polls she was down 7,22,9,7,7. Granted they are from different polling organizations but seems significant to me.
I think its a fairly good bet she is gaining back on Bernie.
jfern
(5,204 posts)Ignoring that obvious outlier of 22 points, none of the differences there are remotely close to being statistically significant.
DCBob
(24,689 posts)I suspect the next poll out of NH has Bernie and Hillary statistically tied.
jfern
(5,204 posts)that the other polls show. Large MOEs of 5 points tend to do that for you.
DemocratSinceBirth
(101,852 posts)Here's the methodology
Respondents were selected from YouGovs and two other online panels. These are opt-in panels which are open for anyone to join. However, YouGov also randomly selected persons from voter registration lists who had previously voted in primary elections and contacted them by phone. (Note: though some respondents were initially contacted and recruited by phone, all interviews were conducted online.) A total of 19,047 registered voters were contacted by phone and the YouGov sample includes 1,163 phone recruits.
https://today.yougov.com/news/2015/09/13/methodology-2016-cbs-news-battleground-tracker/
What possibly could go wrong?
kenn3d
(486 posts)... and yet, when I chose to eliminate that pollster from my customized chart... you said:
FWIW, I considered that yougov poll to be an outlier... (if not an out and out liar).
And that is why I was interested to see what eliminating the internet polls and low-rated pollster data from the composite would show. YouGov is a C rated pollster according to the 538.com rating list and was therefore not included in the chart I posted in #34 below (which calculates only data from A and B rated pollsters):
http://www.democraticunderground.com/?com=view_post&forum=1251&pid=605336
Do you really think the accuracy or value of a composite polling chart is improved by including data from poorly conducted polls? How about the ones Nate rates as D or F or bans altogether?
I still think averages which include outlier biases from poorly conducted polls will only be more biased and less accurate.
Not science (social or otherwise), just my opinion.
DemocratSinceBirth
(101,852 posts)However I used to make small wagers on intrade. I certainly would have ignored that poll in planning my wager.
You always get outliers. Zogby's final CA poll in 00 had Gore down by 1. I would have bet the farm he would win CA and he won it by 12.
kenn3d
(486 posts)But fwiw, http://fivethirtyeight.com/interactives/pollster-ratings/ includes two Zogby polls... one is C rated, the other is rated F.
So if you placed a wager on Gore in CA, I hope you excluded the Zogby poll from your calculations.
just sayin'...
I'm not a betting man, but what few donation dollars I can afford are going to Sanders.
Peace.
ReallyIAmAnOptimist
(357 posts)...well beyond what Obama had done at this point in the cycle.
Bernie has cross party appeal, and the young vote.
Finally, people are fed up with establishment candidates, so everything the pundits and professional insiders think they know is pretty much out the window.
DCBob
(24,689 posts)it doesn't mean either one can win.
frylock
(34,825 posts)did you see the pictures from New Hampshire University of Hillary talking to a half-empty room of baby boomers? About 350 showed up. Meanwhile, in fantasy unicorn rainbow land, Sanders already has 1300 RSVPs for his appearance at the same venue on Sunday. The overflow will be at least double what Hillary drew.
DCBob
(24,689 posts)Don't forget the Ron Paul phenomenon in 2008 and 2012. His supporters packed arenas and were the most aggressive and dedicated out there but in the end it was just a footnote in the political history books.
I see Bernie ending up much the same way.
Bluenorthwest
(45,319 posts)Where you get that he was packing arenas all over the place I do not know. Obama drew thousands more than that in March of 08 at the far smaller University of Oregon, located in not Los Angeles.
Obama's top Oregon crowd was the week of the election, 70,000+ in Portland.
Sanders in Los Angeles, not on a campus, 27,500 estimated crowd. Almost 4X what Paul got on campus. Where is the comparison? There isn't one.
frylock
(34,825 posts)Been hearing the comparison for months now. This isn't Ron Paul's coalition. Bernie Sanders has a Posse.
Joe Turner

Scootaloo
(25,699 posts)She's campaigning as if she doesn't think she should have to. She's cancelled public events to make room for closed fundraisers. She demurs on issue after issue, and when cornered on one - say, black lives mattering - she throws it back in the questioner's face, along with her finger. When she does rise to actually making a move on the campaign, it's to use surrogates against sanders in what, I swear to god, looks more like a parody of attack efforts than actual effort. Trotting out Carlos Danger? This SuperPac bullshit? Naw, she's not taking this seriously at all.
You're right; Bernie Sanders isn't Barack Obama. But he's putting in the work. He's taking his campaign seriously. clinton is as poor a campaigner as she was in 2008, and really seems to be taking this one for granted.
DCBob
(24,689 posts)I suspect her campaign HQ is like a war room with all sorts of strategies, risk assessments, what if scenarios, etc. What you are seeing is the result of all that. The current strategy is to play it cool. That might change if Bernie closes the gap more.
treestar
(82,383 posts)8 years have passed since then. Stuff happened in those 8 years, making the world different than it was in 2007.
The candidates here are different. Hillary may be the same person, but Hillary has also lived through the past 8 years and experienced and done other things and is thus a different candidate from what she was then. The race she is in is different. Then she was running against Obama, Edwards, Kucinich, Richardson, Biden and others. Now she is running only against Bernie basically. Bernie isn to the same person as Obama, etc.

On Sept 16 he was at 25.4%
That's flatlining to me.

(36,063 posts)DCB gets to go to ignore... what I do with name-callers, cheats, devievers, dissemblers and well, liars.
I don't really object to haters for Hillary if they don't screw with the data
DemocratSinceBirth
(101,852 posts)What does it mean?
I do think it's instructive to compare polls to polls performed by the same pollster since the methodology is the same. There are multiple polls from yougov, ipsos-reed, and morning consult.
DCBob
(24,689 posts)This might be useful when the data are very inconsistent. I like the less smoothing option. It provides more insight into the data trends.
morningfog
(18,115 posts)The national polling is still not most important. The current state of things, Hillary isn't due a win til march 1. That's a long time, and a lot can change between now and then.

(101,852 posts)Wow, you are calling NV and SC for Senator Sanders.

DemocratSinceBirth
(101,852 posts)In WAPO and CBS she goes from 20-30 without Biden.
yougov has a subsample where Biden voters break 2-1 to 3-1 for Clinton.
I thought the new Hillary and apology was silly but it seems to be working.
DCBob
(24,689 posts)It's ridiculous that all the polls dont just leave him out.
kenn3d
(486 posts)Here's the same HuffPost Pollster 2016 National Dem Primary chart as in the OP but from Jan 1 2016 to current ... with normal smoothing, AND all the internet polls removed, AND all the poorly rated pollster data removed. Only the six top rated pollsters with A and B ratings from FiveThirtyEight.com are included in this graph.

Probably more accurate than either the default graph at the HuffPo site or the unsmoothed 45 day chart in the OP...
But no national chart will likely predict much beyond name recognition until more nationwide campaigning gears up amongst all the contenders. imo
GOTV!
DCBob
(24,689 posts)DemocratSinceBirth
(101,852 posts)It's also sloppy social science to willy nilly ignore polls you made the subjective determination theyaren't up to snuff...The Law Of Large Numbers equals out the 'good' and 'bad' polls.
DCBob
(24,689 posts)DemocratSinceBirth
(101,852 posts)Even Nate doesn't throw out polls he doesn't like. He just weights them differently.
Sam Wang at Princeton Consortium doesn't weight polls. He just averages them all. Nate gets marginally better results but Wang is truer to the math.
DCBob

(101,852 posts)eom
kenn3d
(486 posts)But I didn't make the determinations as to the quality (and historical accuracy) of the pollsters... fivethirtyeight.com did. All the major poll charting sites (like RealClearPolitics and HuffPollster) use various and different polls, including some and excluding others for who knows what reasons. I just thought is was interesting to see what effect using only top-rated pollsters would have. I really can't see how including lesser quality polling data can improve accuracy once sufficient sample sizes have been met.
Anyway graphing 9 months of data makes trends a bit easier to see than graphing 45 days of data. But I still say the national polls (no matter how they are graphed or customized) are simply not very predictive at this stage. And just getting a graph to show a slight short term improvement for any given candidate is simply fun and folly.

kenn3d
(486 posts)have included Biden since late 2012 or before. You can see this by holding your mouse over the individual plot points.
I suppose it's reasonable for them to assume an incumbent VP is a likely contender whether announced or not. I think the question is at what point in time should he no longer be considered in the polling if he has NOT announced, but speculation is still rampant on that.
OilemFirchen
(7,288 posts)Looks like they included Warren as well.
I wouldn't attempt a trend analysis until all the polls reflect only declared candidates.
Thinkingabout
(30,058 posts)Clearer where voters will go. There will need to be a day of facts and figures, programs are good if there is a way of paying for them.
Let's see what happens. Are her GE polls improving as well? That's the real questioner must win next year with the strongest candidate. Let's hope this is for real not just in the primary but the GE as well about this while email stuff cause if voters don't trust you they won't vote for ya
frylock
(34,825 posts)Do you know how the primaries work?
DCBob

Previous five polls in NH had Bernie up by quite a bit more than that. Granted they were from other polling orgs but still seems significant.

Tom Rinaldo
(23,187 posts)Hillary needed to create a public perception that Sanders was essentially a very minor protest candidate before he gained any real traction in order to avoid a real contest against him. Bernie has the traction he needed already now. He is already highly competition in the first two states up on the calendar. His grassroots fundraising has him well funded already. He just hit the cover of TIME, he just got a hero reception on Colbert, and he has already been validated as a serious candidate because the larger "Team Clinton" has already gone negative on him. Main stream media coverage of Sanders has increased over the last 10 days. And now, finally, a live Democratic candidate debate is looming. Sanders can't be minimized now before then, and that debate is the start of the a new phase in the contest. I'm not Anti-Hillary, I'm Pro-Bernie, and most polling seems to show that Sanders gets support from those who like his message rather than from those who are worried about and so called Clinton scandal. Biden may have gotten some of the latter.

(14,881 posts)check what it means first. Bernie is hardly at "zero" with no heartbeat.
seriously, you can't look at results from one day or week to the next to call a trend. Otherwise, I could claim that Bernie is trending upwards because 2 days ago showed them at 46:25 and now they're at 45:26. Or maybe they have resumed their respective trends.
