The battle for the republican presidential nomination continues, with primaries coming up next in Arizona and Michigan.
Rick Santorum and Mitt Romney continue their fight for delegates with candidates like Ron Paul and Newt Gingrich fighting to stay in the race as well.
Former Mississippi Governor Haley Barbour, who once chaired the Republican National Committee, says the door could still be open for another candidate.
"If the Republican primary voters continue to split up their votes in such a way that nobody is close to having a majority, then there is a chance that somebody else might get in," says Barbour.
Some party members are pushing for New Jersey Governor Chris Christie to put his name in the hat, but Christie says he is still supporting Mitt Romney.
