massive crowd singing aloud and getting the crowd to join him. that's about as unplugged and untethered as you've seen mitt romney in any of his two, now, presidential campaigns, and clearly an exhibition of his sense of relaxed good nature and belief that he's going to pull off a victory here. of course, up until today he'd been pretty far ahead in the polls, so singing is about as risky as you can get. jon: we heard the president singing al green a couple weeks back, i guess mitt romney was inspired to follow suit. what about newt gingrich today? >> reporter: again, sort of trying to look past the current race and position himself for upcoming battles and vowing that he will not get out of the race should he not win the florida 50 winner-take-all delegates and saying he's going to go on for some time, and he's also pressuring rick santorum to get out of the race and allow republican conservatives to coalesce behind newt gingrich which doesn't go over particularly well with rick santorum.
