South Carolina governor Nikki Haley is angry about Newt Gingrich’s comments Sunday referring to Rep. Paul Ryan’s plan to change Medicare into a voucher system as “right-wing social engineering.” From CNN’s Peter Hamby:

Haley, whose promise to endorse a presidential candidate has made her a key power broker in the Republican primary fight, joined in the chorus Tuesday and said she is “terribly disappointed” in Gingrich.
“What he said was absolutely unfortunate,” Haley told CNN in a phone interview. “Here you’ve got Representative Ryan trying to bring common sense to this world of insanity, and Newt absolutely cut him off at the knees.”
“When you have a conservative fighting for real change, the last thing we need is a presidential candidate cutting him off at the knees,” she added.
