Who are they?
Are you still undecided? Why?
They look a lot like the voters who've already locked onto a candidate, though they're more likely to be white and less likely to be liberal. And they disproportionately backed Hillary Rodham Clinton's failed run for the Democratic nomination.
These people trust Obama less than decided voters do to handle the economy, the Iraq war and terrorism. They are less accepting that the Illinois senator has enough experience to be president.
And by a 17 percentage-point spread, more see Republican vice presidential candidate Sarah Palin favorably than unfavorably, unlike the narrow majority of voters already backing a candidate who dislike her.
On the other hand, these wavering voters can be equal-opportunity skeptics. A quarter don't trust either Obama or McCain to deal with the economy and a third are uncomfortable with both on the federal deficit.
"I don't have a feel for either one of these guys," said Jeff Condatore, 47, an independent and computer analyst from Ringwood, N.J. "I don't like any of the choices."
