Ron Paul blasts Gingrich with new ad

Ron Paul's presidential campaign accused his rival former House Speaker Newt Gingrich of "serial hypocrisy" in an ad released on Wednesday.

The 150-second online advertisement notes Gingrich has flip-flopped on climate change and has bashed Rep. Paul Ryan's budget plan as "right-wing social engineering."

It also highlights his work for the government mortgage giants Freddie Mac and Fannie Mae, and his ties to health care companies.

Gingrich earned $1.6 million as a consultant to Freddie Mac, which Republicans have blamed for the mortgage meltdown.

The ad quotes a slew of political pundits and journalists, including conservative radio host Rush Limbaugh and liberal editor Joan Walsh. It concludes with a quote from Gingrich, saying: "It's wrong to go around and adopt radically different positions. Then people have to ask themselves, 'What will you tell me next time?' "

The ad will only appear online and has been sent to a large email list of conservative voters. It comes after Gingrich emerged as the frontrunner for the Republican party’s nomination to the presidency. He was also recently endorsed by the New Hampshire Union Leader, the largest newspaper in the pivotal election state.

“Our campaign is making a bold move 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 Ron Paul 2012 National Campaign Chairman Jesse Benton.
