Pretty much everyone from the George W. Bush administration....the list of high crimes & misdemeanors that pack of thieves, grifters, sociopaths and liars could fill a stadium, to wit:
--Ignoring the August intelligence reports stating that the possibility of a terrorist attack agst. the U.S. was high prior to 9/11
--Playing the idiot ball big-time in regards to the Afghan War...
--...so that they could lie America into a second war in Iraq...
--Deliberately outing a CIA official to the press
--Running the Dept. of Justice as their own private fiefdom and using said agency for partisan purposes (case in point: the various U.S. Attorneys' scandals)
--Squandering a budget surplus left to Dubya by the prior administration to theirs and then adding on top of that w/two needless sets of tax cuts
--The abuse and torture of enemy combatants throughout the years of the Bush-Cheney Administration (and no, just because they were terrorists or evil persons doesn't make it right either)
--Paying news & opinion writers to write pieces favorable to the administration
--Washington's response (or lack thereof) to Hurricane Katrina
--Swiftboating of political opponents for partisan gain (the Repugs' treatment of then-Sens. Max Cleland & John Kerry come to mind on this one)
I could keep going but we'd be here for hours...
