These polls also don’t factor in the crossover vote.
I wouldn’t be surprised if 15 - 20% of the registered Dem votes are gong to Romney.
gong = going
Just from my own personal experience, I would think a lot more Democrats will cross over than Republicans. I don’t know anyone who voted for McCain who is voting for Obama this time. I know a lot of people who voted for Obama in 2008 who are either voting Romney or are not voting for president.
