AND Republicans are more motivated as many suspect,
What are the polls showing about whether people are "very excited" to vote? We don't have to suspect, this is actually a question on surveys.
I'm just stating an objective belief that Republicans will be MORE motivated in '12 than in '08.
Sorry - understand that "more motivated" could be read as "more motivated than Democrats."
Some Republicans were pretty damn motivated by Sarah Palin even if they weren't as anti-Obama as they are now. It was Dem motivation + independents voting heavily Dem that made the difference. But motivation may well be up to vote against Obama even if Romney inspires no one. It happened in '04 with Dems who didn't love Kerry but wanted to vote against Shrub.
