Fifty three percent of “likely voters” favor repealing Obamacare, according to Rasmussen Reports. There are not many issues, save taxes and spending, that will be more broadly discussed and contested. However, the Republican frontrunner, Mitt Romney, will have the most difficult time making the case against Obamacare.

This leads to some interesting questions. A majority of those who favor repealing the health care law are likely Republicans. Will this cause them to reject Romney? If so, do candidates without the national appeal of Romney such as Pawlenty, Bachmann, and Cain even stand a chance, were they to take the nomination. If Romney does win the nomination, does his record on health care drive independent voters who want the law repealed back to Obama?

Equestrian fans, discuss.
