The Dems believe they can take the House and Senate. I do not believe they can or will...the Dems are famous for believing their own (in this case early) polling data. They believe if they can demonize GWB sufficiently, they will win. They won't.
As I said to an earlier post, I don't think the country is suicidal enough, economically or security wise to hand the reigns of power to socialist appeasers either. But, even with no real plan other than to blame the US and bash Bush for everything, including the wheather, it's pretty damn depressing that they are running neck and neck or leading in many polls. Yes, yes I know that polls are not the deciding factor in an election but let's face it if the socialists were 15 points back where they should be the pollsters would have a real hard time spinning their magic.
That they are within striking distance of taking over a local dog warden post is reason to fear for our future.
