Well, I think you are misinformed. I don't know why people of your persuasion keep on drinking the Kool-Aid and watching our country be ripped apart by this dismal little man we now have in the White House.
People far more learned than me who actually know the law agree that Bush has committed impeachable offenses:
"Former Nixon White House counsel John Dean called Bush 'the first president to admit to an impeachable offense.'"
Regarding domestic spying authorized by Bush: "The American public has to understand that a crime has been committed, a serious crime," Chris Pyle, a professor of politics at Mount Holyoke College and an expert on government surveillance of civilians, tells Salon. "Looking at this controversy objectively, you inevitably end up with a question of impeachment," says Jonathan Turley, a professor at the George Washington University School of Law.
"Turley is no Democratic partisan; he testified to Congress in favor of Bill Clinton's impeachment. "Many of my Republican friends joined in that hearing and insisted that this was a matter of defending the rule of law, and had nothing to do with political antagonism," he says. "I'm surprised that many of those same voices are silent. The crime in this case was a knowing and premeditated act. This operation violated not just the federal statute but the United States Constitution. For Republicans to suggest that this is not a legitimate question of federal crimes makes a mockery of their position during the Clinton period. For Republicans, this is the ultimate test of principle."
I'm not going to debate all your other "points" but just wanted to bring this to your attention.
