If the Republicans take the House and Senate and do right by this country, Obama won’t run in 2012. He’ll quit before being voted out.
Johnson didn’t bother to run in ‘68 but didn’t resign. That seems more likely to me, but a lot can happen between now and then.
Without the ability to force legislation through the Senate, the best the Republicans can do is defund Obastard, Pelosi, and Reid’s legislation. I would also like to see them force all the unconstitutional czars out of the White House.
