Des Moines, Iowa (CNN) - For the second time this week, a new TV commercial by Rick Perry paints some of the his rivals for the Republican presidential nomination as Washington insiders, while touting the Texas governor's anti-Washington credentials.
Perry's presidential campaign tells CNN that the new 30-second spot will start running Thursday statewide in Iowa, just five days ahead of the January 3 caucuses, which kick off the presidential primary and caucus calendar.
As the narrator in the ad says "the fox guarding the henhouse is like asking a Congressman to fix Washington: bad idea. Their years in Congress left us with debt, bailouts. Congressmen get paid $174,000 a year. We get the bill," pictures of former House Speaker Newt Gingrich, Rep. Ron Paul of Texas, Rep. Michele Bachmann of Minnesota, and former Sen. Rick Santorum of Pennsylvania appear up on the screen.
The spot goes on to include Perry saying "I've called for a part-time Congress. Cut their pay in half, cut their time in Washington in half, cut their staff in half, send them home. Let them get a job like everybody else back home has."
The commercial is very similar to an ad the Perry campaign launched on Iowa TV on Monday.
Perry first floated his proposal to make Congress "part-time" last month as part of his plans to reform Washington.
The long serving governor jumped into the race for the GOP presidential nomination in mid-August and soon soared to the top spot in the polls, but after numerous stumbles in debates this autumn, his poll numbers sank. Perry has been touting his anti-Washington credentials as he tries to jump start his campaign. He's in fifth place, at 11% support, in a CNN/Time/ORC International poll of likely GOP caucus goers that was released Wednesday.
As of Dec. 25, the Perry campaign had spent more than $1.5 million to run ads on Iowa TV.
