I can't watch it now, but was everyone even asked the Palin question? Even so, I can imagine a situation where McCain was running against Clinton, and they'd vote for Clinton over McCain anyway. Maybe they even liked Obama because they thought he looked like a nice guy and felt he was trustworthy, issues aside. Either way, it's not neccessarily a race thing.
The editing of that segment and the comments on the blog are looking for an excuse to vent their frustration, and letting a race issue color (no pun intended) their judgement. It's ridiculous.
Posted this in the funny videos thread, but apparently McCain's own campaign felt the same way. Straight from the horses mouth, on the O'Reilly Factor earlier tonight:
