The Senate won't vote in it. Reid won't allow it.
It’s not unheard of for the GOP to find ways to force a vote on something despite its minority status. For ex, an amendment can be proposed to a bill that is coming up for a vote. Sometimes this works.
DeMint is good at forcing votes. I suspect he will find a way.
The post entitled Making Boehner's Bones has a nice analysis of tactics that could force the repeal through the Senate and get it signed, or, alternatively, lay a government shut-down at the feet of Obama and Reid.
In fact, short of that tactic working, the real hope for getting rid of it before January 2013 is the court challenges. The repeal moves are mostly a matter of keeping faith with the voters and keeping the issue alive so it hurts the left in 2012.
