We've been told this will be considered at the Convention in Tampa. I think they'll be waiting to see if they need to forgive the FL GOP their primary transgressions and award all 99 FL delegates to Mitt if it will help him to 1144 delegates and the nomination -- or if they can do the right thing and give Newt his share (those delegates where to be awarded proportionally if the contest was held before March 1 -- and FL moved their primary to Jan 31). They accepted being docked to 50 delegates but awarded them all to Mitt, even though Newt won close to 32% of the popular vote -- to Mitt's 46%. And Newt won the majority of Congressional districts).
What they said after the Florida election was that if no candidate has clinched the nomination by April 1, the other candidates can challenge the Florida delegation and split the Florida votes.
So, if both Santorum and Gingrich request that, I think they would have to do it. It wouldn’t do much for Gingrich, he as too far to go, but it would hurt Romney.
