A Democrat and a Republican talk about the speculation over what's in Mitt Romney's tax returns:

Republican: Wow, it was really irresponsible of Harry Reid to say someone told him Mitt Romney had paid no taxes of the past decade.

Democrat: How so?

Republican: Well, Reid doesn't have any proof. He's just got speculation.

Democrat: And you think if he's going to make a claim about what's in Mitt Romney's tax returns, then he should offer proof?

Republican: Exactly.

Democrat: Fair enough. But by that standard shouldn't Romney prove that he's telling the truth about his returns?

Republican: This isn't about Mitt Romney. It's about Harry Reid.
