Piers Morgan's hour-long interview with new GOP front-runner Herman Cain airs tonight, 9pmET, and the candidate talks about race and growing up in the South, his views on gay marriage and abortion, his battle with cancer and much more. He also gives his take on the rest of the GOP field. "Speaker Gingrich and Governor Romney are the two that I have the greatest amount of respect for," he says. "That I would feel comfortable if I did not get it."

And who does he respect the least?

"I don't believe Representative Ron Paul would be a good president," he tells Piers Morgan. "If you listen to his position on a lot of things, it's always, let's throw out the baby with the bathwater."

Watch the full interview tonight, 9pmET/PT.
