If Romney Wins SC, It's Over: Graham

Stephen Colbert (ahem, rather, his Super PAC) may have been ripping "serial killer" Mitt Romney today, but real politicians were also getting their licks in on the Sunday shows, reports Politico. Most eyes were on the Palmetto State's primary on Saturday, and cue the fat lady if Romney wins, say two South Carolina Republicans. "I think it should be over,” Lindsey Graham said. “I hope the party would rally around him if he did in fact win South Carolina.” Added freshman Rep. Tim Scott, "I think this is the last stand for many candidates." Elsewhere on your Sunday talk-show extravaganza:

• There's no fat lady and she's not singing, says Rick Santorum: Rather, it's down to Romney and Santorum. “I’m not going to tell anybody to get in or out of the race," he said, adding that "once we get it down to a two-person race, we have an excellent chance to win."
• Romney's not a shoo-in, says Newt Gingrich: "I think the only way that a Massachusetts moderate can get through South Carolina is if the vote is split,” Gingrich said. “But we have six days to make our case to people.”
• Hits on Romney are legit, says Rick Perry: “We’re going to get tested by Obama so you better have all of these answers done early. No surprises in September or October.” Further, "it's our intention to win South Carolina and go forward from there."
• Jim DeMint will not endorse a candidate: "I'd feel fine about any of the candidates," says the SC senator, adding that eventually "I think Republicans will be very united." Graham and Scott also declined to endorse a candidate.
