(CNN) – Two influential conservative politicians in South Carolina predicted Sunday that Mitt Romney will effectively wrap up the Republican presidential nomination if he wins the upcoming Palmetto State primary.
Sen. Lindsey Graham and Rep. Tim Scott, both Republicans, told NBC's "Meet the Press" that a Romney victory in South Carolina on January 21 would end the suspense after the former Massachusetts governor won the first two contests in Iowa and New Hampshire.
"If for some reason he's not derailed here and Mitt Romney wins South Carolina, no one's ever won all three, I think it should be over," Graham said. "That would be quite a testament to his ability as a candidate and a campaigner."
On the same program, Scott said: "If Romney wins South Carolina, I think the game is over."
The comments followed a meeting of influential Christian conservative leaders over the weekend that resulted in an endorsement of former Pennsylvania Sen. Rick Santorum in an effort to prevent a split among voters on the religious right.
Scott, who won his 2010 election with heavy backing from the tea party movement, said the impact of the evangelical vote - a typically large voting bloc in conservative South Carolina - will be "huge" on Saturday. However, he added that Romney will benefit if evangelical Christian voters are divided between Santorum, former House Speaker Newt Gingrich and Texas Gov. Rick Perry, as polls have indicated.
"It's hard to find a single candidate that rallies all of the Christian voters in South Carolina and therefore that splintered approach will probably have a major impact in the state's primary," Scott said.
