Would a Romney nomination kill O-care repeal?

Just as John McCain was able to win the Republican nomination in 2008 despite his problems with the conservative base, Romney may be able to overcome his health care record in the primaries. And perhaps there are circumstances under which he could beat Obama by emphasizing economic and foreign policy issues. But win or lose, Romney would not be able to credibly campaign against the national health care law. And as a result, were he the Republican nominee, it would kill the movement to repeal ObamaCare.
