Nothing. Iowa is a likely Obama state.
Dems usually vote early. Rep show up on election day. The whole reason the Dems pushed this early voter scheme was to give their lazy ass voters more time to vote.
The exact opposite is happening in NC where Dem ballots are significantly down from 2008 and significantly less then GOP early ballots.
BTW National Journal is a wholly owned Democrat Party propaganda organ. You would be wise to simply ignore them.
The last real (Ras) poll I saw on Iowa had Romney by 3.
I was linked to National Journal by another site. I agree that National Journal is a Dem site but whoever is reporting it these are hard numbers so my question is this a normal pattern for Iowa as I’ve never even been to that state.
