Ron Paul expands Iowa buy with Gingrich attack ad

“We wanted to ensure this ad reached as many voters as possible, to debunk the myth that the Newt we are seeing on the 2012 campaign trail is the conservative he has been touted to be all along,” said Paul campaign chairman Jesse Benton in a statement.

The libertarian Texas congressman is hoping that his passionate base and strong organization will propel him to victory in Iowa, where Gingrich has not spent the time or resources to establish an effective ground game and Romney has never been able to gain traction.

“The voters are looking for authentic conservatives who are able to show a decades-long career of consistently walking the walk of Constitutional principles, limited government, and promoting sound economic policies," Benton said. "Ron Paul is the only Republican presidential candidate with that record.”

Paul placed second in a PPP poll of the state released earlier this week, trailing Gingrich by 9 points but leading Romney.
