I think at this point it is a hollow gesture to gear up for the 2012 elections. There is bipartisan support, maybe even enough to pass, but not even close to veto override support. There is no way that Obama signs this bill, and without enough support to override his veto why bother now.
I would rather them wait and see what happens in 2012 so they don't offer the excuse that they tried but it didn't work.
I hope my gut feeling is wrong, but I'm not holding my breath.
