The one interesting thing that is happening (and IA is a key part) is that it is becoming theoretically possible for Romney to (barely) win without winning Ohio.
If Obama gets...
NV - Likely according to approval rating and Paul-tards
PA - More skeptical recently, but seems to be safe Obama
then he only needs Virginia, Michigan and Ohio and he wins.
Virginia might be slipping out of reach unless the Romney camp does something soon. Ohio (ignoring weighted polls) seems to be close, and Michigan, while it leans toward Obama, has 10% undecided, which is good news for Romney.
One thing is for sure, we need Florida. There can be no question about us winning Florida. The recent story about Dem registration failure looks good for that state.
