About yesterday's polls...

2. OK, but Clinton's numbers were very high, too--until she actually started running.

She had very high approval as Secretary of State. As Presidential Primary candidate Clinton, her numbers have gone down.

We don't know whether or not Biden's numbers will trend similarly, but the current numbers are really for Vice President Biden, not for Presidential Primary candidate Biden. Historically, he has not done very well in the latter capacity--although now, as VP and as someone outpacing both Bernie and Hillary in the polls, his fundraising ability will be yooge.

What we do know is that ALL Bernie's numbers are for Presidential candidate Sanders because he had little name recognition before he started running. So, the more people hear him, the more his numbers should continue increase.
