Huckabee is NOTHING like McCain or Graham. It is fine to not like a candidate, but it is wrong to slander them.
Huckabee was one of the major campaigners for Graham this cycle. He hitched his wagon to that star and absolutely he will now reap what the harvest of that alliance.
His pathetic attempt to backtrack (in which he tried to employ the “depends on what the meaning of the word “is” is” strategy) when the meaning of his add was clear pretty much finished him with a lot of people.
