Before you flip out about the Newsweek poll...

...see this post from Powerline:

UPDATE: Reader Meg Kreikemeier points out that according to RealClearPolitics, Newsweek's most recent poll included 345 Republicans, 364 Democrats and 278 independents. This compares to Newsweek's published data for their most recent prior poll, which showed President Bush with a comfortable lead: 391 Republicans,300 Democrats and 270 independents. Yes, if you drop 46 Republicans and add 64 Democrats, you will get considerably better results for the Democratic nominee. This is a good reminder of why poll data always need to be taken with a grain of salt, especially until you see the underlying data.
