PolitiFact verified several days ago that Santorum's claim that Gingrich has supported some version of the mandate for 20 years was "mostly true." But it didn't think to ask whether Santorum, too, has supported the individual mandate in the past. And as it happens, he has. He supported it in 1994, according to this April 7, 1994 article in the Allentown, Pa. Morning Call, and this May 2, 1994 article in the same newspaper. It's possible that the newspaper would have gotten this wrong once, but in the heat of a primary campaign it's highly unlikely Santorum's campaign would have allowed it to get this wrong twice.
