Has anyone thought of this dirty trick though?
Our next president?
He and Cheney could resign between Jan 6 and Jan 20, 2009. Then Nancy Pelosi (Speaker of the House) would have the choice to become president and give up her seat, and her Republican Governor would replace her with a Republican. If she refuses, then Robert Byrd (President Pro Temp of the Senate) would have to consider giving up his seat and being replaced by his Republican Governor with a Republican.
So since they'd both probably pass, then Condeleeza Rice (Secretary of State) would fill the void and become the first black president and the first female president for a few days. She'd take away Obama's legacy. How's that for a dirty trick?
P.S. It won't happen. Byrd's governor is a Democrat and Byrd is so old that he might like being president for a few days and then retiring. I had you going for a second, didn't I? ;)
