As a native Iowan, I knew Mitt Romney wasn't a good candidate for the state. He's lost two state caucuses and he's going to lose the state on Tuesday. Bad candidate.
Interesting because the last month I've been all over Iowa and I've seen a lot of support for Romney and hardly any for O.
As far as this poll, they have a problem with their LV screen and EV data is screwed up, keep trying to tell you alot of these polls are messed up b/c of this. And No I don't think this one is biased, just bad data.
