WASHINGTON D.C. -- The GOP presidential candidates are pulling out all stops ahead of Super Tuesday.
The Republican race is so intense Mitt Romney went to Washington state, where they caucus tomorrow but pick no delegates.
Romney needs any boost and a win tomorrow would be good going into next week's mega primary.
On Super Tuesday 424 delegates are at stake in 11 state contests, roughly a third of the total needed to win.
The primaries in Georgia and Ohio matter most.
Rick Santorum's lead in Ohio polls shrank to six today.
Ohio is more conservative and religious than Michigan, where Santorum narrowly lost last Tuesday.
If he can win there, it will change the face of the race.
"If he can win Ohio, he shows that he can beat Mitt Romney. Then you get a one-on-one match up, and if you're the more passionate conservative in a one-on-one match up with a weak frontrunner like Mitt Romney, you've got a shot," says CNBC's John Harwood.
Georgia is Newt Gingrich's home state.
He's playing up his roots, leading polls there by double digits.
