Santorum ad derides Gingrich moon plan


Newt Gingrich's plan to colonize the moon drew more ridicule today in a new radio ad out of the Rick Santorum camp.

As Santorum seeks anew to climb over Gingrich among conservatives in Nevada and elsewhere, the 60-second spot that his campaign says is airing nationally called the idea "fiscal insanity."

"And another reason true conservatives are uniting behind Rick Santorum," it says.
