Look for Mitt Romney’s campaign to put a renewed focus on snuffing out Newt Gingrich, despite his poor showing in last night’s N.H. primary. Team Romney worries that the former Speaker has nothing left to lose and will amp up his kamikaze attacks on the likely nominee, including buys by the pro-Gingrich super PAC, which last week got a $5 million check from billionaire casino magnate Sheldon Adelson. The new attacks will fall under the “unreliable leader” rubic that Romney rolled out when Gingrich looked like a real threat in mid-December. Gingrich was never going to be competitive in N.H., but could still run strongly in the primaries in S.C. (Jan. 21) and Fla. (Jan. 31). So Romney, leery about potential fallout from Newt’s promised Bain Capital jihad as the campaign moves to S.C., plans to keep a boot on his throat.
