14. Team Clinton should be most concerned about that favorability rating.

First, there's very few undecided. That means she doesn't have much room to change it. People already like her or dislike her, and it's harder to change an established opinion than getting a "don't know" into "favorable".

Second, that favorability rating is underwater. That usually means the support is not very strong. "A mile wide and an inch deep". That indicates there's an opening for someone else to come along and vacuum up those unhappy supporters. If this was a "needs to screw up royally" situation, the favorability score would be much better.

Long story short, Clinton needs to "run out the clock" on the primaries. The sooner they end, the better for her. And the less exposure to all Democratic candidates in the media, the better for her. Because she's in front, and she's unlikely to gain more support because of that tiny "don't know" in favorability.

Sanders or O'Malley need the opposite: They need lots of exposure to get those "don't knows" into "favorable" in order to get reluctant Clinton supporters to switch. Basically, what Obama did in 2008.
