Though it's no secret that Mitt Romney's income is made up of residual Bain investments taxed at the low rate of 15%, the candidate admitted it this morning at a campaign stop in Florence, South Carolina. “It’s probably closer to the 15 percent rate than anything,” Romney said. According to the Times, he also loses his speaking fees in the cushions of his couch. “And then I get speaker’s fees from time to time, but not very much.” Yeah, what's $374,327, or nearly 14 times the per capita income of Americans?

15% is also considerably lower than what Romney told last night's GOP debate moderators what his ideal maximum tax rate would be: 25%. He also repeated last night's "wait until I'm definitely the nominee before you can see my tax returns" line: "I know that if I’m the nominee, people will want to see the most recent year, and see what happened in the most recent year and what things are up to date and so they’ll want to see the tax returns that come out in April."
