2020 Democratic Ticket -Kander/Harris or Kander/Booker

Jason Kander-MO is the ideal Democratic challenger to Republican incumbent Donald Trump. He is under 40 years old- he is likely to do well with millennial voters. He is former Army Intelligence Officer-he has foreign policy/national security experience. He narrowly lose a US Senate Election 2016 in a red state-MO against a Republican incumbent-Roy Blunt-campaigning as a progressive.
Kander will need to select a black US Senator Kamala Harris-CA or Cory Booker-NJ to win battleground states in the Midwest that have a strong black electorate
OH-18 (250ev)
MI-16 (266ev)
WI-10 (276ev)

Red State Democrats Steve Bullock-MT and Jason Kander-MO running in 2020 for higher office.

Steve Bullock is unable to run again for a third term as MT Governor due to term limits. His next option is running for US Senate against Republican incumbent Steve Daines but the 2020 MT US Senate Race between Steve Daines-R and Steve Bullock-D is going to be a tossup with Daines having the advantage. Bullock is better off seeking the Democratic nomination for President in 2020. He can put MT in play.
Jason Kander narrowly to the 2016 MO US Senate state against Republican incumbent Roy Blunt when Trump defeated Clinton in MO by an 19 percent margin. MO other US Senate seat is up in 2018 but it is currently held by a Democrat-Claire McCaskill. Kander could run for MO Governor in 2020 against Republican incumbent Eric Greitens but Kander is better off being on the 2020 Democratic Ticket as Bullock's VP runningmate.
A Bullock/Kander ticket could carry all of the Clinton 2016 states 232ev and at a minumum turn PA,MI,and WI into blue states.

According to wikipedia, VA Governor Terry McAullife-D has publicly expressed interest in a

2020 Presidential run.
Terry McAullife's successor as VA Governor assuming he wins the Democratic primary and the November 2017 General Election- Tom Perriello-D would be the perfect Democratic nominee for President in 2020. He is a progressive Democrat who represented a conservative District while he served in the US House for 1 term from 2009-2011. He also served as US Ambassador to a region in Africa. Since VA Governorship is a 1term limit state and both VA US Senate seats are held by Democrats, Perriello could run for President in 2020.
If Perriello is the 2020 Democratic Presidential nominee, Julian Castro-TX would be the perfect VP runningmate.
If McAullife is the 2020 Democratic Presidential nominee, Kamala Harris-CA would be the perfect VP runningmate.

Pros and Cons of a Warren-MA/Brown-OH ticket in 2020

Pro
Warren and Brown are both strong progressives and Brown can help Warren win the Rust belt states ie PA,MI,and WI. OH will be a tossup state.
Con
Brown would be 68 in 2020 and 76 in 2028.
The current Governor of OH in 2021 would be a Republican -Mike Dewine. Dewine would then appoint John Kasich to Brown's OH US Senate Seat. Kasich-R would be favored to win in the 2022 Special Election.
Before Brown gets considered as the Democratic nominee for VP or President, We first need to elect a Democrat to the OH Governorship in 2018, Richard Codray- the former OH Attorney General and current head of the Consumer Financial Protection Bureau-position Warren held before she got elected to the US Senate.
Another person that Warren could select as her VP runningmate is NC Governor Roy Cooper. Cooper would help Warren win FL and NC. GA will be a tossup state. Cooper would have to give up the NC Governorship unless NC Democrats could select Deborah Ross or Anthony Foxx to run for Governor and/or US Senator in 2020.

The leading contenders for the 2020 Democratic Presidential nomination based on high

name recognition, ability to energize the progressive Democratic base and win the November General Election are going to be Elizabeth Warren-MA and Martin OMalley-MD. The Democratic party establishment base headed by fellow Marylander Tom Perez-current DNC chair will in 2020 coalesce around Martin OMalley. Hillary Clinton,John Kerry,and Al Gore will be portrayed as losers, Losing a winnable Presidential race against a controversial Republican opponent Bush43 and Trump. Bernie Sanders is going to be in his late 70's. OMalley is the most experienced candidate for President, former Mayor of Baltimore-1999 to 2007, former Governor of Maryland-2007 to 2015. OMalley also ran for President in 2016, Losing in the Democratic primary to Hillary Clinton who was the favored by the establishment wing of the Democratic Party and Bernie Sanders who was favored by the progressive base of the Democratic party. OMalley could then appoint Former HUD Secretary Julian Castro-TX as his Vice Presidential runningmate. Omalley/Castro ticket could carry the Clinton 2016 states 232ev plus pick up AZ,FL,and NC-287ev or pick up PA,MI,and WI-278ev.

Anthony Foxx-NC/Julian Castro-TX or Julian Castro-TX/Anthony Foxx-NC is the ticket that could lead

Democrats to victory in 2020.
Both of these guys are former Cabinet Secretaries under Obama and former city Mayors meaning they have the experience to perform the duties of the President/Vice President. Both of these guys are from a minority ethic group (African/Hispanic)- it could increase voter turnout in the African American/Hispanic American community helping Democrats win AZ,NC,and FL along with the Clinton 2016 states-287ev. Both of these candidates could appeal to White Moderates from the suburbs.
Foxx-NC has a better chance getting over 270ev needed to unseat Trump/Pence than unseating US Senator Thom Thillis-R in November 2020. Same goes for Castro-TX regarding unseating Cruz-R in 2018 or Cornyn-R in 2020.
