From Tuesday night’s Fox News All-Stars.

On Rick Perry’s flat tax plan:

I think this is the beginning of his re-launch — and his last chance for a re-launch.
What’s surprising is that he didn’t start with this. He thought he could start the campaign defining himself as a guy that created jobs in Texas. That is not enough. That is a bit of a narrative, but it’s not a program.
When Reagan ran in 1980 he had a program. He wasn’t only running against stagnations and Carter and malaise, he ran on policy … the Kemp-Roth tax cuts, which were radical. [A] one-third cut …
His is of equal sweep. The problem is we’re not sure where the revenues are coming from. Remember, we’re starting with a deficit of $1.3 trillion already. Now he’s going to cuts the tax on dividends, on capital gains, on income, on business and corporations, and [will] zero [out] estate taxes. …
But you have got to show me some numbers. There will be some extra revenue from [tax-cut induced] growth. But if you start with a $1.3 trillion deficit and you cut all the five major categories of taxes, you’ve got to show me where your [spending] cuts are going to be. And I’m not sure he has done that. He’s going to have to.

On the suggestion that Perry accounts for spending cuts by promising a balanced budget amendment:

You say you are [going to balance the budget] because it’s in the plan — there’s going to be a [balanced budget] amendment. But it’s easy to say you will balance the budget. You’ve got to show me where spending cuts will be.

On Perry’s recent comments on the birther issue:

It’s a sign of tremendous lack of discipline. The answer is: The case is closed. It’s a quick, short answer. You don’t say: I’m not sure, I don’t know, and you start up on this issue. It’s a loony tunes issue.
If you want to be a serious candidate, you’ve got to say that’s already done, it’s closed, it’s not an issue. Period.
