The Latest: Cruz breaks off SC campaign for Scalia Mass
Ted Cruz has taken time away from campaigning in South Carolina to attend the funeral Mass in Washington for the late Supreme Court Justice Antonin Scalia.
The Republican presidential candidate plans to be back in South Carolina later Saturday to await the results.
Bush says he's going to "work hard for the day" and await results after the polls close at 7 p.m. He says "it's interesting that a lot of people claim they're undecided this late."
Rubio is trying to rebound after a disappointing fifth-place finish in New Hampshire — and he's hoping the popular governor's endorsement will be a big boost.
Without a strong showing in South Carolina, the Bush campaign may have a hard time competing in Nevada next week and then in the large number of states voting on March 1.
A Donald Trump victory could foreshadow strong showings in Southern states that vote on March 1 — when he could pile up the delegates that determine the nominee.
Ted Cruz hopes his get-out-the-vote operation and lots of volunteers can help overtake Trump in South Carolina.
