How was Obama doing Summer of 2007?
About 20 points behind Hillary nationally, 5-10 points behind and tied with Edwards in Iowa, and 15-20 points behind in New Hampshire.
Currently, Bernie is about 35 points behind Hillary, 25-30 points behind in Iowa, and 5-10 points behind in New Hampshire. So, not impossible to pull an '08 repeat, but a very, very big uphill climb.
Yeah, I still can't imagine Hillary losing this either. That said, in Iowa and New Hampshire, while he's trailing Hillary by much bigger margins, his % of support if higher than Obama's was at the same time, as seen in Mehmentum's post above. Seems the difference is Hillary is just much stronger than she was 8 years ago.
