Even if there were a way to challenge proportionality in Florida, no one in the state party has shown any interest. Lenny Curry, the state GOP chairman, on Thursday painted Gingrich's campaign as a sore loser for making the argument.
Gingrich's campaign circulated a memo on Wednesday questioning whether Romney won all 50 delegates or whether they should be proportional an "unsettled question which will not be resolved until the Republican convention in Tampa this August."
Former Florida Attorney General Bill McCollum, Gingrich's state chairman, reiterated that point on Thursday morning.
"You've got to realize that whoever was going to lose was going to make this challenge," he said on Fox News. McCollum said the challenge would be brought "to contest committee, then on convention floor."
Gingrich has argued his campaign will go to the convention, and this is likely his way as painting the nominating contest as a fight for delegates instead of racking up primary and caucus wins.
It takes 1,144 delegates to win the Republican nomination. Mitt Romney has 71; Gingrich has 23; Rick Santorum has 13; Ron Paul has three; and Jon Huntsman has two, according to a count by The New York Times.
