A liberal, a conservative and a moderate walk into a bar' in new Santorum radio ad hitting Romney, a LDS member

Following a trouncing by Mitt Romney in the Puerto Rico GOP primary, the Santorum campaign has chosen to use funds for a new radio ad starting off with joke.

"A liberal, a moderate, and a conservative walk into a bar," the ad narrator proposes over subtle guitar picking. "And the bartender says 'Hello Mitt.' Funny, but true."

Totally.

The joke sets up the ad's message that Rick Santorum's rival candidate Romney does not seem to have any core values, "just says what he thinks people want to hear," giving examples of Romney's much scrutinized pro-life record and the latest alleged flip-flop in regards to making English the official language.

"Where does Romney stand on the issues?" the ad closes. "It all depends on who he's standing in front of."

The ad was paid for by Rick Santorum for President.

Maggie Haberman notes that the ad uses the same 'bar joke' recited by Santorum's top super PAC donor Foster Friess at CPAC.

Luckily for the Romney campaign their candidate, a member of the Church of Latter Day Saints which prohibits its members from drinking alcohol, is unlikely to show up in a bar any time soon.
