Des Moines, Iowa (CNN) – Mitt Romney has added two veteran Republican operatives to his small team in South Carolina as the state's primary nears.
And a super PAC backing Romney's presidential bid is now running television ads in the Palmetto State attacking the immigration stances of Newt Gingrich and Rick Perry, two candidates who hope their southern roots help them appeal to South Carolina voters.

In a sign of their increasing confidence across the early state playing field, the Romney campaign has signed up Warren Tompkins and Luke Byars to help run political operations in the state before the January 21 primary.
Tompkins told CNN Friday that they are both serving as advisers in a volunteer capacity.
"Right now I want to help, and they wanted our help, and we're going to do whatever we can do to help them out," said Tompkins, who said he traveled to Boston in November to meet with Romney campaign manager Matt Rhoades.
Both Republicans worked for Romney's fruitless 2008 effort in South Carolina. Byars is also a longtime adviser to Sen. Jim DeMint.
They join Romney's South Carolina state director, David Raad.
The staff hires were first reported by The State newspaper in Columbia.
Unlike the vast and expensive campaign operation he ran in South Carolina in 2008, Romney currently has just four paid staffers and one office in the state, which holds the first southern primary and has a tradition of accurately picking Republican presidential nominees.
But Romney and his team are betting that momentum, a flurry of television ads and a recent endorsement from Gov. Nikki Haley might be enough for a South Carolina win in a fractured Republican field.
The Romney campaign is currently running television ads in some of the state's media markets.
They were joined this week by the super PAC, Restore Our Future, which is now airing a television ad in the state called "Too Much." The ad is already running in Iowa.
The 30-second spot accuses Perry and Gingrich of favoring lenient policies for illegal immigrants and claims both candidates have "too much baggage on ethics."
