Gingrich on Fox News Sunday:

WALLACE: You say Mitt Romney. McCain started an exploratory committee this week. Thirty seconds: Are you going to do the same?

GINGRICH: No. We have a program called American Solutions we're working on. And in September of next year, I'll be glad to come back and talk with you about running for president, but not until...

WALLACE: Not until that late?

GINGRICH: Not until September.

A Newt run would certainly shake things up.
