Yes there is a dark current running throuh the Republican party right now. But I see the Democratic party as a bunch of scatterbrains who can only yell "wrong" about everything GWB does.
That's why I say we would be better off with no plotitcal parties.
The political pendulum swings both ways. Right now it is on the Republican side and it will surely swing to the Democratic side soon. All the Rush Limbaughs in the world can't stop it.
