Yet more evidence that the polls are simply too unreliable at this point. Support shifts back and forth by the day and there are more than, what, 40 days left? NBC/WSJ has it at Obama 48, McCain 46 with a 3-point margin of error. Independents seem to be making up the ground he’s lost on the economy.

McCain has done a better job wooing independent voters than he did last month. Among registered voters who describe themselves as independent, 34% supported Obama and 49% supported McCain.

That is a big swing from August, when Obama led among independents 46% to 35%. That is, in part, because that fluid category of voters this month included a larger portion of white men without college degrees, a group Obama has a hard time wooing…

Palin’s nomination was a plus for McCain among Republicans and independents: 43% of GOP registered voters and 38% of independents say they are more likely to vote for McCain because of Palin. Only 2% of Republicans and 18% of independents said she made them less likely to support McCain.

NBC has McCain with a 13-point lead amongst Independents, which is a significant improvement from a 5-point lead just 2 weeks ago.

It should be noted that Rasmussen also has Obama up by just two, though that’s an improvement for Obama in that specific poll. Gallup has The One leading by 3, which is and improvement for Maverick in that one. Oy vey.
