Of course those national polls are unimportant compared to those being conducted state-by-state where the election will be decided. There's a new wave of those out today from two news organizations that paint a similar picture of a very tight race.
McCain's selection of Sarah Palin and the rallying of the traditional conservative base appears to have given the senator a boost in some of those red states which the Obama campaign has targeted. In Virginia, a new CNN/Time magazine poll has McCain up 50 percent to 46 percent, while another poll by the same shows him leading in Missouri by a similar 50 percent to 45 percent margin. In Florida, a new Quinnipiac poll has McCain up even more, 50 percent to 43 percent.
But there are troubling signs for McCain in the state of Ohio, which played such a pivotal role in re-electing President Bush in 2004. A Quinnipiac poll there has Obama leading 49 percent to 44 percent. Quinnipiac also has Obama up by a slim 48 percent to 45 percent margin in Pennsylvania while CNN/Time has him leading McCain in New Hampshire 51 percent to 45 percent and up 49 percent to 45 percent in Michigan.
For all the excitement generated by the Palin pick among Republicans, these polls numbers should be have a cooling effect. It's encouraging for McCain that in two big "blue" states – Pennsylvania and Michigan – remain highly competitive. Pulling either of them into the GOP column would highly complicate Obama's path to the White House. But losing Ohio, so vital to GOP hopes in the past, would make winning one of those other large states essential.
The Buckeye State is where Hillary Clinton scored a big but too-late victory in the primary season and where questions about Obama's ability to attract those white, blue-collar, Reagan Democrats started really being raised. His lead in Ohio at this point in the campaign is perhaps the most significant of all these polling results.
Of course there will be plenty more polls out in the coming days and weeks, each one given more import than the last. In the meantime, check out our Ways To Win interactive map and plot your own path to the presidency for both candidates.
