Problem is lack of overt enthusiasm doesn’t mean the Obamites won’t vote for what they now consider the lesser of two evils
Back in 1964 I would walk home from school along Woodmont Boulevard in Nashville and take bumper sticker polls. About every other car had a sticker. I thought Goldwater would win but did not realize my neighborhood was not bellwether precinct. My SUV and my wife's mini-van are tacky with so many TEA Party, skateboard, and Romney stickers.
Just returned from early voting at the library in the little town of Dunnellon, FL. There was a line of about 20 or so people, but it moved quickly. Everyone in line was friendly and relaxed - no discussion of anything political, just family and work stuff. Turnout seems the same as last year, but this is a very Republican area.
