OK, Mark,
Given that Obama can veto any bills passed by a Republican Congress, the reinstatement of Dubya's tax cuts probably won't go through before early 2013. But I think that if the Republicans take control of Congress this fall, Obama will be officially defeated in 2012, along with Republicans retaining control of Congress, because of the factors we've already cited (control of voter registration, voting machines, congressional redistricting, media ownership consolidation, limitless campaign spending by corporations, big corporations wanting Republicans to win, etc.)   So those tax cuts for the ultra rich and for income acquired by means other than wages/salaries will be reinstated in the near future.
