Oh, I'm sure we can think of something to come up with.
My point is that I dont think we should impeach for imeachment sake. Impeachment is bad for the nation, and unless the alternative... allowing a bad criminal to continue running the country is worse, impeachment should be avoided.
Now if an investigation turns up that Bush clearly knew no WMD were in Iraq and pushed for war with that reason anyway... I think impeachment would be in order... Thus far I have not seen any good evidence he knew for a fact Iraq had no WMD!
