Sorry to object, and to strenuously object, but it's w-a-a-a-a-a-a-y too early to be bothered by polls.
I've seen this all my life; the only polls that illuminate are those taken just before an election, like a week or a few days before. Polls taken months and months before elections don't mean squat.
The only usefulness one can get out of early polls is an early indication which way people are trending, and candidates usually have a campaign staff to devise strategies to influence people to gradually swing in their favor.
I've lived my whole life through this; I'm not seeing anything I haven't seen before.
Barry "Goldwater" Obama is bound to make some major gaffe somewhere along the line, and by late October, we're going to see the same thing we saw in 1972 and 1984, the big-city machine bosses abandoning the top of the ticket and working desperately creating votes to save those Democrats further down the ballot.
Wait and see if I'm not right.
I wish I could articulate why I feel this way--muddyemms asked me to, but I couldn't--but there you have it, my gut instinct. Wait and see if I'm not right.
