Driving several hundred miles around Iowa on Friday, it didn't take long to hear some political ads on the radio for the Iowa Caucuses.  There were some postivie spots from Rick Perry and other candidates - and then one hard hitting ad against Newt Gingrich.

That 60 second ad on Gingrich was everywhere - on a country music station, a sports talk station and an FM rocker.

It's paid for by an outside Super PAC that's been linked to Mitt Romney called "Restore Our Future."

Check out this ad against Gingrich - will it hurt Newt?  Will it hurt if Gingrich doesn't really respond to it?
