In a new television ad to be aired in Iowa today, Texas Gov. Rick Perry characterizes himself as the outsider and truth-teller who will put aside "political correctness" to overhaul Washington, D.C.

"Washington is the capital of political correctness, where double speak reigns and truth is frowned upon," Perry says as he looks directly into the camera. "You can't say that congressmen becoming lobbyists is a form of legal corruption or that we give aid money to countries that oppose America. Or that Washington insiders are bankrupting Social Security. You and I know it's true, but not politically correct. I'm Rick Perry, an outsider who will overhaul Washington and tell you the truth."

Perry's new ad, the latest in the campaign's million-dollar advertising push in the final weeks before the Iowa caucuses, comes the day before he begins a 42-city bus tour through Iowa Wednesday.
