Okay, I live in a suburb of Seattle, WA; so, there is no chance of WA going red; but, I live next door to an African-American (older) couple and he always, ALWAYS has Democratic candidate signs hanging off his front fence during election season. We have lived next door to this couple for over 30 years --- always the same.
Last election, Obama/Biden signs on his fence --- this year, none, zero, nada. There is one sign for a local man running for a State Rep seat; but, no Obama/Biden sign. I am gob-smacked about that. If the "O" has lost my neighbor, he is in deep trouble.
Some additional anecdotal evidence is this:
I live in a Dane County WI suburb of Madison. When we were going through the whole recall thing there were hundreds of Recall Walker signs everywhere, union officials everywhere drumming up support to oust Walker.
Now it is very quiet. Hardly an Obama sign to speak of and no union people on street corners trying to raise support for 0.
The GOTV effort for fending off the recall is still in place and is as effective as it was in June, Wisconsin will be close, but it will go for Romney 51% to 48%.
IMHO!
