Is Herman Cain a viable Presidential Candidate in today's GOP; more than Romney, Palin or Pawlenty?

Is he viable against well known heavy hitters like Romney and Paul? No. Is he viable against candidates like Bachmann, Johnson and Santorum? Yes. As much as I love Herman Cain, there is a part of me that realizes in order for Obama to be defeated in the next election, he has to be put up against a major political player - like Romney. Cain would be popular, to be certain, but he wouldn't be a strong enough contender to defeat Obama and secure the presidency.
