Except we're not talking about Sanders v Clinton here mate that's done and over with Clinton is the presidential choice. So that data is next to useless.Where this falls down is that Sanders is actually popular with moderates.
On a sample of 51,078, Clinton beats Trump by 47% to 42%. However, Sanders beats Trump by 52% to 40%.
2,927 would vote for Sanders in an election, but not Clinton. Which just goes to show how absurd this political race is.
Of the 2,927 who would vote for Sanders and not Clinton, 35% identify as Republican and 33% as Independent. In other words, Sanders seems to be having a pulling effect on moderates and Republicans that Clinton is not reaching.
You can read and look at a bunch of other infographics which seem to be telling the same thing: Sanders wins over the moderates.

The questions is what benefits her more for a VP choice Sanders or Kaine. I expect the DNC and Clinton are far better at judging than us. Afterall they are nowhere near as incompetent as our Labour party currently is.
