The finish line is in sight for GOP Presidential candidates in Florida, with primaries set to be held on Tuesday.  And as they gear up for the sprint to the finish, Newt Gingrich picked up a high-profile endorsement over the weekend.

FOX News Radio's Chris Stanley reports:

It was in Florida where Herman Cain had a surprise straw poll win last summer, and it was in Florida where he decided to finally back another GOP candidate.

(Cain) "I hereby officially and enthusiastically endorse Newt Gingrich for President of the United States."

(Cain) "I know that he's going through this sausage grinder because he cares about the future of the United States of America"

Cain, who dropped out of the race in November in the midst of allegations of sexual harassment and marital infidelity, is still popular with grassroots conservatives.

Another candidate, meanwhile, missed his events Sunday morning.  Rick Santorum spent the day in Philadelphia, where his terminally ill daughter, Bella, was hospitalized after developing pneumonia in both lungs.

Another of Santorum's daughters, Elizabeth, took her dad's place on the campaign trail in Sarasota, FL:

Former Florida Governor Jeb Bush hasn't announced an endorsement of any candidate ahead of Tuesday's primary.
