Rick Santorum says he's under no pressure to quit the GOP presidential race so conservative voters can coalesce around Newt Gingrich.
The former Pennsylvania senator tells CNN's "State of the Union" that his campaign is building momentum even after a third-place finish in South Carolina. He says he expects to run well in Florida's Jan. 31 primary.
Santorum says the suggestion that conservatives will have to coalesce to beat former Massachusetts Gov. Mitt Romney is "objectively false."
Santorum points out that he beat Romney in Iowa and says Gingrich "smoked him here in South Carolina."
Santorum says that while Romney has more campaign money, he has the better ideas and message to inspire voters.
