Well played, sir. Well played. Sen. Harry Reid seems to have put Mitt Romney into a bit of a box: His campaign will have to confirm or rebut the charges, because it'll be pretty damned hard to ignore. It's quite a surprise coming from Reid, who's not known for this kind of openly aggressive behavior:

WASHINGTON -- Senate Majority Leader Harry Reid (D-Nev.) has what he says is an informed explanation for why Mitt Romney refuses to release additional tax returns. According a Bain investor, Reid charged, Romney didn't pay any taxes for 10 years.

In a wide-ranging interview with The Huffington Post from his office on Capitol Hill, Reid saved some of his toughest words for the presumptive Republican presidential nominee. Romney couldn't make it through a Senate confirmation process as a mere Cabinet nominee, the majority leader insisted, owing to the opaqueness of his personal finances.

"His poor father must be so embarrassed about his son," Reid said, in reference to George Romney's standard-setting decision to turn over 12 years of tax returns when he ran for president in the late 1960s.

Saying he had "no problem with somebody being really, really wealthy," Reid sat up in his chair a bit before stirring the pot further. A month or so ago, he said, a person who had invested with Bain Capital called his office.

"Harry, he didn't pay any taxes for 10 years," Reid recounted the person as saying.

"He didn't pay taxes for 10 years! Now, do I know that that's true? Well, I'm not certain," said Reid. "But obviously he can't release those tax returns. How would it look?

"You guys have said his wealth is $250 million," Reid went on. "Not a chance in the world. It's a lot more than that. I mean, you do pretty well if you don't pay taxes for 10 years when you're making millions and millions of dollars."

The highest ranked Democrat in Congress, Reid is known more as a back room brawler than a public flamethrower. So his willingness to throw this private conversation into the media frenzy over Romney's taxes underscores the low opinion he has of the Republican candidate.
