IA-CNN Dems: Hillary 50, Sanders 31

[Bakersfield Uber Alles]

It definitely looks like Biden could benefit Sanders as shown in pretty much every other poll with/without Biden. I would be curious to see how this would continue to play out if Biden actually enters. I could see Sanders losing a bit of support from people who mostly liked him because he isn't Clinton. I do think that it wouldn't affect Sanders too much (and would still lower the margin between Hillary and Bernie).

urban:

Clinton 46%
Sanders 37%

rural:

Clinton 54%
Sanders 21%

I'd be interested in more polls that have rural/urban numbers. I remember that some of us (myself included) thought that Sanders would do well in Iowa because of the large rural population reminiscent of Vermont. Maybe it would play out in somewhere more rural like North Dakota?
