Rick Santorum Calls Mitt Romney "Serially Untruthful" on Health Care Record (Wikipedia)

Rick Santorum says Gov. Mitt Romney “serially” untruthful and “deliberately” misrepresenting his health care record. In other words, he’s a liar. This GOP slugfest continues and it’s hilarious.

The Hill:  “What I’d like to talk about, which is offensive, is Gov. Romney out there for almost a year telling people in the Republican primary that he never advocated that RomneyCare would be a federal model, that he never advocated for the individual mandate that would require people to buy insurance,” Santorum said Thursday in an interview on CNN. “And now we find on several occasions just in the last week, article after article, interview after interview, where Gov. Romney did just that.”
