If one believes this poll — and keep in mind it's only one poll — more Americans want Bush and Cheney impeached than ever wanted Bill Clinton impeached.
It's kind of an odd way to look at the situation. In order to impeach those guys, someone would have to come up with one or more specific crimes with which to charge them…and the poll doesn't even ask about one. While a clear majority of Americans might wish Bush and Cheney were gone, I'm not sure they'd agree on a particular impeachable offense…or that the administration will ever yield sufficient evidence or comply with the subpoenas necessary to make that case…or that the current Supreme Court would compel them to cooperate. Methinks Bush and Cheney could go around robbing 7-Eleven stores at gunpoint and Antonin Scalia would say, "Oh, yes…they're allowed to do that. And by the way, my ruling is non-precedential."
Besides, even if you could prove High Crimes and Misdemeanors, how do you impeach both men at the same time? That's got to be a legal nightmare of procedural rulings, most of which would wind up before the Supreme Court, which did everything in its power to put those guys into office in the first place. If you impeach Bush first, then Cheney becomes president, which even most Republicans wouldn't want. It would be interesting to see Cheney try to name his successor…and I suppose that he'd also argue that he can't be impeached as president for crimes he may have committed as vice-president…and back we go to the Supreme Court to rule on that. On the other hand, if you impeach Cheney first then Bush would try to name a successor and would also argue that any crimes he may have committed were actually the doings of that snake, Dick Cheney.
I don't think there's any chance of impeaching these two fellows, no matter how much America may dislike them. But it is going to be fun watching Democrats keep the possibility alive and Republicans distancing themselves from the White House.
