Death panels and dead grandmas didn't work, so the Republican focus has shifted from "kill the bill" to repeal it:
You're not thinking like a Republican. They are going to urge their base to vote in record numbers to repeal the bill, in the hopes that Democrats turn out in fewer numbers. They don't have to state WHAT they will repeal, because anything they name in the bill will hurt their chances of re-election in the first place. All they need to say is that a vote for a Republican means reversing the government take-over that Obama signed into law. They don't even need to succeed in repealing the bill - they just need to succeed in getting the votes to put more of their members into Congress.
