Everyone on this thread is thinking a too long time frame when talking 11/2012. Its the 11/2010 elections that are going to be the ball game.
The GOP delusion is in thinking they can stop the Obama agenda on various reforms, they will be rewarded by the American people in the election of 11/2010. Which is the same exact GOP delusion the GOP operated on in stopping any of the democratic agenda in the last two years of GWB. And while the GOP was immensely proud of itself in largely blunting all the democratic agendas during the 2007-2009 time frame, when it came to for the American people to reward the GOP, they got a rather ugly dope slap at the polls instead.
Right now Obama may be rather naive on thinking that the GOP can be reasoned with or will be anything other than obstructionists, but with some patience, all good things may come to democrats who wait, because after the election of 2010, there may not be enough republirats left to even bother to consult.
After all, many of these reforms are decades and decades over due, will a year and two months really matter? Its what sustained the policies of Reid and Pelosi during the last dark days of GWB, as they were smart enough not to shut down government just to have their way, and even now the GOP tries to shut down government while it still has the last vestiges of the tyranny of the minority.
Oh, how much further can the proud party of Lincoln and Teddy Roosevelt still fall before there is nothing left?
