I'm in the Pittsburgh market and suspect the reason the TEA PARTY ads don't air so much is that they were ineffective. It was our TEA PARTY in SW Pennsylvania who supported Tom Smith over the GOP-e endorsed RINO in the April primary, the guy who finished third.
and I saw the first Smith sign yesterday; no Casey signs yet.
Then there's this; my Dad is a lifelong, dyed in the wool Dem. His foundest hope is to go to his reward and never ever vote for a republican, but you know what, he's not voting this year. First time ever.
And I have to believe there are many old time dems in the same boat; they will not be able to vote for Obama, but they just can't vote for Romney.
Philadelphia. I'm in the city a fair amount. There are less Obama signs than you'd expect - far, far less than in 2008. The sole Casey sign I've seen has been in the suburbs.
