I never write diaries, so bear with me a little. The NBC/Survey Monkey poll that keeps being mentioned as proof of Hillary's crushing Bernie (polls are about a month apart):
Biden: 10 15 11 7 7
HRC: 45 41 49 48 50
Bernie: 31 29 25 26 5
That is the voter preference question, not the 'who won the debate' question. Bernie is up 2. Biden is the big loser. This is not bad for Bernie, considering that most of Biden's votes were supposed to go to Hillary, and most people think she won the debate (in this poll). Sure, it's an online poll, but they do have a good methodology, and as far as I know this is the only post-debate poll so far asking who would you vote for.

Not bad at all.
