Both the veracity and the motivation of your assertions are open to question.
Nonetheless, let's proceed, for a second, as if they are true.
1. If the current and prevailing opposition to the administration's health care plan can somehow be attributed to is moniker, we should not expect that to change anytime soon. Even the liberal left employs the term "Obamacare". Furthermore, the impact of the act's provisions will not be felt in sufficient time to change anybody's mind. If the act, or parts thereof, eventually serve to ameliorate the public's distaste, this will certainly not occur prior to November.
2. Your second assertion is, undoubtedly, the more "controversial" of the two. However, if we, reluctantly, assign it some degree of merit, then we might also suggest that any politician running lock, stock and barrel with Obama's agenda might be subject to those same forces. They will easily be seen as a surrogate, if you will, for the black man in the White House. Conway may be white, but so is Rand, and those unfortunate souls motivated to cast a vote exclusively on the basis of "skin color" will not be pulling the lever for Barack Obama's avatar.
Now, did you have a third point to make?
