Paul attacks Gingrich in new Iowa ad

The 60-second ad will run starting Wednesday in conjunction with Paul's ad released Monday that calls him the "big dog" when it comes to cutting federal spending.
"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," Paul national campaign chairman Jesse Benton said in a statement.

The "serial hypocrisy" video was e-mailed to conservatives in Iowa and other early voting states last week. It uses Gingrich's own words on climate change, Medicare and his post-congressional career of offering "strategic advice" to mortgage giant Freddie Mac.
Paul, a Texas congressman, is running second and an average of 11 points behind Gingrich in the latest Iowa polls, according to recent surveys compiled by RealClearPolitics.
Gingrich starting running his own ad in Iowa on Monday that emphasizes his love of America and his prescription for the economy.
