I for one cannot believe this country would impeach Clinton for lying (although one can argue whether or not gettin some head in the oval office is sexual relations or not) and not impeach Bush for flat out lying to get us in a war on "terror".
Well, last I checked, people were more concerned about sex than violence (the survey was applied to video games, but it can theoretically be applied to a lot of things (sorry, I can't remember where I read that, but it was very recent))
Also, Clinton was close to home, "oh god think of the children!" (imagine a shrill, over-reacting mother screaming this and you'll get the right image) that got massive public attention. Also, it happened in the States. The war, (and no offense to the soldiers out there, you've my respect for just being there) while much more dangerous, bloody and expensive, is "over there", "out of sight, out of mind", is covered with propaganda and bullshit from the media and the government here.
Sexual misconduct fires people up a lot more than just violence, or terror.
Besides, Bush is getting dumped out of office anyways, and history will hopefully mark him down as being a complete idiot. Nothing can be as worse as destroying your name throughly enough so it goes down in history as mud.
Rambling now, shutting up.
