On the bright side, a proper ruling from Scotus would preclude the Kenyan from the ballot in 2012."
First, of course SCOTUS can't "kick" him out. They don't enforce the law.
However, how would that work if they find him ineligible for 2012, yet somehow eligible now? Or, are you suggesting that after finding him ineligible (for 2012), that he would simply remain in office now?
Once the "proper" case gets to them (SCOTUS), they would be hard pressed to find someone born a subject to the crown of her majesty the Queen of England to be considered a Natural Born Citizen as known and intended by the framers (& subsequently reaffirmed by founder Ramsay, the dicta of 5 SCOTUS cases and the author of the 14th Amendment).
Born in country, to citizen parentS.
If SCOTUS finds him ineligible, and by that time there is an R majority, I would assume they’d get him out. Impeachment’s too good for him, since he isn’t a real president anyway. But maybe they’d do that.
