(CNN) – Two days before her state's primary, Arizona Gov. Jan Brewer on Sunday endorsed Mitt Romney for the Republican presidential nomination.
"I'm going to publicly endorse Mitt Romney. I think he's the man that carried the day," Brewer said on the NBC program "Meet the Press."
The endorsement is considered a boost for Romney in Arizona, a conservative state where he is favored in Tuesday's primary against rivals Rick Santorum, Newt Gingrich and Ron Paul.
"I think he has that pro-business background and he has that political history that I think he would serve America the best of all the candidates," Brewer said, adding that Romney also has the best chance of defeating President Barack Obama in November.
The governor met with several of the candidates last week as they campaigned in the state and took the stage Wednesday at CNN’s Republican presidential debate in Mesa.
Brewer said she believes the outcome of the Republican race will be clear after the upcoming Super Tuesday contests in 10 states on March 6.
"I think that after Super Tuesday we'll have our candidate," Brewer said, acknowledging her view differs from what most pundits say. "I think that overwhelmingly it will be decided."
