The Clintons may have had some sort of cocaine allegations on the Bushes, but I think it's all part of the good ole boy network. Politicians of both parties close circles and defend each other regardless of the charges. It's just bad taste to go against your former adversary when it comes to politics. Look at Bush Sr. and Clinton chumming around. What is going on with that? And look at these clowns in the Senate calling each other, "my illustrious colleague from the other side of the ailse". It's disgraceful. We are never going to see these Republicans fight because they are protecting their own little empire and don't want to upset the apple cart. That's waht a two party system gets us, corruption.
You're right. Two parties = collusion and corruption. But I think there must be more to it than that, maybe I'm just cynical and paranoid.
