What will an Obama vs. Cain presidential campaign look like? It will be, to say the least, "fascinating," The Nation‘s Melissa Harris-Perry says on MSNBC’s Sound Off. Cain has been a leading GOP candidate in many states and surely the most competitive African-American Republican candidate so far. Harris-Perry points out that his campaign signifies the ideological complexity in African-American communities, and as long as he doesn’t reveal his ignorance on topic such as foreign policy, his folksy appeal will have some resonance.
