I am not a fan of Erin Burnett of CNN, but every now and then, she does her homework:

Obama deputy campaign manager Stephanie Cutter n CNN

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.

Burnett: Okay, they’ll just say that you can do that. They’re are other studies. I know the one to which you’re referring, but there’s also the possibility of economic growth.

Cutter: Prove it. Erin, prove it.
