The Tampa Bay Times reports that Mitt Romney's super PAC is currently up with a new radio ad in Florida's radio markets:

For those who might have missed it, Fox News’s Greta Van Susteren interviewed Newt Gingrich last night and asked whether he was “backing down” on his “attack on Bain capital.” Gingrich replied:

Columbia, S.C.
Over the past few days, Newt Gingrich and his super PAC have been attacking Mitt Romney as a "corporate raider" for his work at Bain Capital, and Gingrich has faced considerable pushback from many on the right. While campaigning at the Palmetto Senior Show on the Columbia fairgrounds today, Gingrich pivoted from the Bain attacks and said the reason some "so-called conservatives" are going after him is because he wants to know how the Wall Street bailout money was spent.

Here are Gingrich's remarks at the Palmetto Senior Show:

Elliott Abrams, writing in the Wall Street Journal: 

The Wall Street Journal Asia editorial page is covering the uptick in verbal attacks on Hong Kong individuals and institutions by Chinese Communist officials and their official press.

I’m flattered to be welcomed by Karl Rove, writing in today’s Wall Street Journal, to membership in the GOP establishment. I’m even more pleased by Rove’s statement that “No group of power brokers can pressure others into uniting behind one candidate. Millions of primary voters and caucus-goers will select the GOP's nominee. That's good enough for most of us.”

Ridgeway, S.C.
Although a top aide to Rick Santorum says the campaign currently has no plans to run negative ads in South Carolina, Santorum himself is throwing jabs at each of his GOP rivals on the campaign trail. While speaking yesterday at a small-town cafe called Yesteryears, Santorum painted Newt Gingrich as soft on illegal immigration, Ron Paul as weak on national defense, Rick Perry as a hypocrite on earmarks, and Mitt Romney as "maybe a little better" than Barack Obama.

Fred Barnes, writing in the Wall Street Journal:

Earlier this month, the Obama administration came out with a plan for the country’s defense and its military needs. It is a bold, even radical, plan that dramatically alters the nation’s strategic outlook. So of course it received almost as much media attention as the shouting matches between Valerie Jarrett and Robert Gibbs, three years ago, over an indiscreet remark the first lady had made in France.

An Insider Advantage poll from South Carolina, taken after the New Hampshire primary, shows Mitt Romney with a narrow lead over Newt Gingrich.
