My quick advice. Take a look at libertarian, the best ideas of democrats and republicans in a sensible way. Now if they could just find a candidate to get people excited.
On the impending Democratic take-over of Congress. Yes it is important to oust as many Republicans as possible, if only because it will create a stalemate with the Executive branch. Not always a great thing, but in looking at the alternative, a much more attractive situation IMHO. Take away the yes men and Bush will be forced to listen to another opinion and maybe one day compromise on something (ok, now I am dreaming).
