TAMPA -- A few things to expect tonight:
Newt and Callista Gingrich are giving a speech together; they alternate speaking every one to three sentences. I suspect that this will be a little weird.
Jeb Bush is giving a speech focusing on education; a teacher and a student who benefited from his school choice policies in Florida will appear with him.
Mitt Romney's lieutenant governor, Kerry Healey, will discuss his record in Massachusetts. Romney's friend and former coworker Grant Bennett will discuss Romney's good works as a Mormon lay pastor.
Clint Eastwood is making a surprise appearance.
Marco Rubio will introduce Romney, whose big speech will, of course, be the main event.
