Best we can hope for is a republican takeover of the senate in 2010. There probably won't be enough wins to take the house, though. It's the house that brings articles of impeachment to the senate for trial, and as long as you have Pelosi and Bawny Fwank et-al in charge of the house it ain't gonna happen.
For now, the citizenship question to be finally answered with documented proof one way or the other needs to happen soon. Along with his college paperwork to see what name and nationality he used to get the foreign aid student grants and who paid for his Harvard Law School education. Was it the House of Saud? No wonder he did that deep, respectful bow to the king last week. He owes them a lot.
Unfortunately, Obama is spending millions in legal fees to make sure those documents never see the light of day.
I know, there are many here who will say "it's a done deal, nothing to see, move along..." but until we really have access to all the facts NOTHING IS A DONE DEAL.
The congress in it's present configuration will never impeach their savior.
