I believe these polls do routinely slant against Republicans, but people should stop dismissing them. The standard response to miserable GOP polling on this forum and others is to point out that Democrats were oversampled. Very often true. The problem is, right now, more people are identifying themselves as Democrats. The reason for this is simply that more and more Americans don't think Bush is doing a very good job.
Iraq is the center of all this discontent. The "Muslim Democracy" mission is destroying Bush's presidency. Period.
Even worse is the fact that the President communicates poorly in too many venues. His simple straightforward approach is great some of the time, but he simply hasn't the ability to speak coherently off the cuff or in front of audiences that aren't exceedingly friendly to him.
The Bush Administration's PR/communications team is awful. Scott McClellen is amongst the worst Press Secretaries Ive every seen.
Bush only stays afloat because the American public generally trusted him to kill terrorists and keep America safter than the likes of Kerry could. Sadly, the ports deal is undermining even that.
I don't see why more people would be identifying as Democrats than Republicans. Republicans have lost some battles, but Democrats have lost nearly all of them over the last 5 years. At least Republicans succeeded with our Supreme Court picks, pro-life agenda, and tax cuts. What victory have the Democrats accomplished? Scooter Libby? LOL
