Of course he would. Romney finished second in Florida last time and is not angling for a repeat -- especially as a win for Newt would generate talk of momentum (or Newtmentum, as it will likely be called). The Romney campaign unleashed this ad last night, in which a 1990s Newt essentially brags about his insider status.
With a week left before the Florida primary, the TV-ad war in that state is likely to be loud and fierce as Gingrich and Romney battle it out. According to Kantar's CMAG, TV spending in 2008 topped $10 million -- and that was a race with only three candidates. This time, four remain standing, and the Super PACs have been set free. Some estimates peg the number at $15 million this time around, but the forces aligned with Gingrich and Romney could drive it higher.
