Despite new infusions of cash, former House speaker Newt Gingrich is still being crushed in Florida television ad spending by former Massachusetts governor Mitt Romney.

With the primary coming up on Jan. 31, Gingrich and his supporters are being outspent 5-to-1 by Romney and his supporters as total spending in the state approached $20 million.

According to a Republican media buyer who provides the Post with television ad numbers, Gingrich’s campaign has spent only $1,112,541 on Florida television ads.

The pro-Gingrich super PAC Winning Our Future has spent $2,164,727, despite a $5 million contribution from the wife of casino mogul Sheldon Adelson, who already donated $5 million to the group.

A spokesman insisted that the group was spending the $6 million it had promised to invest in the Sunshine State, but so far that money has not been put into TV. The total pro-Gingrich television spending so far is only $3,277,268.

Romney, meanwhile, has spent $6,723,288 and the pro-Romney super PAC Restore Our Future has spent $8,815,227 for total Romney-supporting spending of $15,538,515.

Part of Romney’s dominance stems from the fact that his super PAC supporters began putting money into Florida way back in December, and he began spending money himself in early January, while Gingrich and his supporters have only been airing ads in the state for the past few days.

The American Federation of State County and Municipal Employees, meanwhile, has spent $954,250 on an ad attacking Romney in the state.

Rep. Ron Paul (R-Texas) and former Sen. Rick Santorum (R-Pa.) both decided not to spend any money on Florida ads. Paul completely ignored Florida; Santorum insists he’s not giving up on the state but said his campaign competing on TV there was too expensive.

“We felt that it was too risky to just bet on the race in Florida when it’s going be winner-take-all,” said Santorum adviser John Brabender. “One of the two candidates who have spent a fortune has made a grave mistake, we just don’t know which one yet.”
