McCain likes to work with Democrats. With a Democrat majority in Congress, he could get a lot done -- all of it bad.
Clinton and Obama's ideas maybe (slightly) worse, but at least then the Republicans would act the part of an opposition party and try to block their worst impulses. I expect to vote for Hillary. I think the resulting damage to the country -- and especially to the GOP -- will be less than if McCain achieves the White House.
McCain IS a Democrat. There is nothing in his legislative record that says anything else. The only thing that distinguishes him from the other two Democratic candidates is his experience as a POW and comparatively dismal academic record.
I wonder if McCain is still waiting to speak with German Chancellor Putin. Moron.
