The Democrats aren't interested in the reasons for the firings, they are only interested in gaining access to protected communications between the Attorney General's office, Cheney and Rove. They want to prove that Rove instigated the firings as part of a political vendetta. They wouldn't even allow any testimony on the real reason for the firings, just on who instigated it.
One of the federal prosecutors, who refused to prosecute ACORN, was here in WA state. ACORN handed the governorship to Christine Gregoire on the third recount. The prosecutor claimed that he did not have evidence of a conspiracy because he had no tapes or any evidence that the cheating was planned.
I get it. Thanks for the explanation, I must have missed that before.
