Has lying liar Stephanie Cutter been hanging around “Honest Joe” Biden too much? She seems to have developed an uncharacteristic penchant for truth-telling.

First she admitted Romney won the first presidential debate in Denver. And yesterday on CNN, she conceded that Mitt Romney isn’t actually planning to run up a $5 trillion tab via tax cuts.

Earlier this week, Sen. Marco Rubio said that Joe Biden is “the best thing we’ve got going.” But good ol’ Stephanocchio is doing a heckuva job vying for runner up.

Partial transcript via Breitbart TV:

Erin Burnett, CNN host: So you’re saying if you lower them by 20% you get a $5 trillion tab, right?

Stephanie Cutter: It’s a $5 trillion tab.

Burnett: But then when you close deductions it’s not going to be anywhere near $5 trillion, that’s our analysis.

Cutter: Well, okay, stipulated. It won’t be near $5 trillion but it’s also not going to be the sum of $5 trillion in the loopholes that he’s going to close. So it is going to cost someone and it’s going to cost the middle class. Independent economists have taken a look at this. There aren’t enough deductions for those at the top to account for the number of tax cuts that they get because of Mitt Romney’s policy so you have to raise taxes on the middle class. As Bill Clinton said, it’s just simple math.

Evidently, simple math is hard.

One Twitter user helpfully translates Cutter’s use of the word “stipulated”:
