WASHINGTON -- Arizona Gov. Jan Brewer endorsed Mitt Romney ahead of her state's Republican presidential primary on Tuesday.

"I think he's the man that can carry the day," Brewer said on NBC's "Meet the Press." "Mitt is by far the person that can go in and win."

Brewer says she had looked at all the candidates and decided to endorse the former Massachusetts governor because his business background appealed to her.

"I think that he handles himself very very well, he has that pro-business background, he has that political history, that he would serve America the best of all the candidates," Brewer said.

"I think he'd serve Americans the best of all the candidates," Brewer added, noting that she thinks he's the candidate who could win November's election.

The endorsement came four days after Romney and three rivals appeared in a debate in Mesa, Ariz. The former Massachusetts governor is expected to win Tuesday's contest in Arizona, which is home to a significant Mormon population.

Whether Brewer's endorsement will make a difference in the Arizona primary is yet to be seen. Other endorsements from GOP governors have failed Romney in the past, including Governor Nikki Haley's endorsement in South Carolina, where Romney lost to Newt Gingrich.
