The last 5 Iowa polls within the last half of October, post debate, without Biden.
Clinton (+7, +11, +3, +38, +41)
lol, I guess Web and Chafee's voters relocation really help out Clinton.
But boy, is this #s so varied.
Also, I recalled there was an article that said Trump's supporters are irregular voters. A large chunk of Sanders' supporters in Iowa seemed to be either just came to college in 2011 and later (aka current under grad college students).
And if they are college students, hell, they would care about the midterm election and or wasn't old enough to vote in 2012. Not many young people care about midterm election.
