Because you’re trying to move the independents you have to draw stark contrasts between you and your opponent. Romney’s doing that, but Obama continues to pray and spray. He hits himself a lot.
What I suspect is happening is Alxerod doesn’t want to lose the base and have them stay home. A lot of this expenditure is simply to keep the base engaged.
Imagine poor Pres. Obama - he moves left he loses 2/3s of voters. He moves right and he loses his base. I’m most surprised that Romney’s Boston groupies pivoted fairly quickly on this and have done a great job of landing blows. They have to stick with it until Nov. 7, though.
Obama wasted millions on the Baine meme. A political rope-a-dope.
