Well, Mitt Romney didn't take President Obama's deal (essentially, release more tax returns and we'll stop talking about them). So here's a new Priorities USA Action ad using Romney's interview Thursday to hammer his tax rate.

The ad notes that under Paul Ryan's "Roadmap" (though not under the budget passed by the House GOP) Romney would pay almost no taxes.

"Small-minded" is airing in Colorado, Florida, Ohio, Iowa, Pennsylvania and Virginia.

The script:

ROMNEY: “The fascination with taxes I paid I find to be very small minded…I’ve paid at least 13 percent.”

NARRATOR: But under one of Paul Ryan’s budget plans, Romney would pay only 1 percent. That’s right. Mitt Romney’s worth $200 million dollars, but under Paul Ryan’s budget, he’d pay only 1 percent in taxes, while middle class families would pay $1000 more. Romney and Ryan. If they win, the middle class losses.
