From my own polling amongst those who keep up. (Which is few). After Fred dropped out it went decidedly Romney.
Going from a Conservative giant like Fred to a pathological lying liberal sleaze makes as much sense as dropping an anvil on your privates from a great height. You should still cast your vote for Fred.
Same thing I'm hearing here in TN from those who keep up with things. I'm just worried about the folks who don't. Sigh.
