Frankly, I think the best argument for electing a Democrat as President is that as long as a Republican is in office the media powers-that-be will refuse to condemn even the worst atrocities on the part of Islamists, for fear of helping the real enemy in the White HouseI'd have to agree. Democrats have been blinded by partisanship so much that they really have lost site of the very real fact that Islamic terrorism will be a world-wide force regardless of which party has the White House. It is the height of stupidity and arrogance to even suggest that Iraq or George Bush have made violent Islamists hate America. Osama bin Laden and his ilk despise the West because we're not Muslim. He feels similarly about Muslims who do not share his particular brand of Wahhabi Islam.
It's arguable whether America's political leadership ought to be stating this fact on a regular basis; it's essential that they operate with this assumption, however.
Just as only Nixon could go to China, perhaps only a Democrat can defeat radical Islam. At this point, Hillary Clinton and Bill Richardson are the only Democratic candidates who realize this.
