OK Congressional Republicans, here are the facts: The Affordable Care Act (ACA), which you derisively call "Obamacare", is the law of the land, duly enacted by Congress, signed into law by the president, and upheld as constitutional by the Supreme Court. You don't like it but it's time to get over it and move on. The "death panels" that you so conspicuously (and falsely) predicted have not materialized and the civilized world as we know it has not come to an end.
You propose to "Repeal and Replace" the ACA, but I wonder why. The key provisions of the law are based on principals which were originally proposed by Republicans and conservative "think tanks", so what is it that you object to, really? And replace with what - I follow the issue pretty closely and I have not seen a serious proposal for a program to replace the ACA advanced by any Republican politician. So "repeal and replace" may have a nice ring to it in a campaign speech but it seems like a pretty empty phrase.
I have a suggestion for you: embrace the ACA as your own; call it "Romney Care" if you want to, because there's really no substantive difference between the Massachusetts health care law that Romney championed and "Obamacare". Then set out on a path to implement the law in a meaningful way instead of putting obstacles in place to delay or curtail its effectiveness. Nobody thinks the ACA is perfect so there is plenty of opportunity for you to advance ideas to improve the law and make access to affordable health care a reality for all Americans - replace "repeal and replace" with "implement and improve". Don't do it because it's politically expedient, do it because it's the right thing to do for the American public (you do remember us, don't you?).
Show America, and the world, that you are capable of putting the interests of your constituents ahead of the billionaire plutocrats whose only interest is maintaining the status quo, because it makes them even richer than they already are. You are capable of that, aren't you? And if you are worried about losing a wedge issue that can help you defeat Obama in 2012, well the economy still sucks so if you focus on that, instead of "Obamacare", you should still stand a pretty good chance.
