If someone accused me of not paying taxes, I’d tell them to show up at a press conference with me the next day, and show some proof, or see my lawyer.
And at the press conference, I’d bring 10 years of cancelled checks to the IRS - with the amounts blotted out (how much I pay the feds is no business of Harry Reid’s, or anybody else, for that matter).
As pointed out in numerous threads, this ploy is simply a means to get ammunition to use against Romney - whatever they find, they will distort, and the MSM will lap it up. Standard Obama election strategy, only much less efficient than digging up old divorce records.
