Mesa Mayor Scott Smith said Wednesday he will drop out of the race for the Republican gubernatorial nomination if Gov. Jan Brewer decides to pursue another term.

Smith has been in the race for just a few days and said his fledgling campaign was going well.

But he said in an interview with Arizona Public Media that he would defer to Brewer if she tries to run again.

“I’m not going to be one to challenge if she makes a decision to run," Smith said. "Others may choose to do that. If the sitting governor of the state chooses to run for reelection I would certainly reconsider what I am going to do.”

One other has said he would legally challenge the governor.

Secretary of State Ken Bennett, also a GOP gubernatorial candidate, said more than a year ago that he would legally challenge Brewer's right to seek what would be a third term.

Article 5, Section 1 of the Arizona Constitution says the governor is limited to two terms in office. The Constitution defines a term as “any part of a term served.”

Brewer took over from Gov. Janet Napolitano in 2009 and served two years before she was elected to a full, four-year term. She said earlier this week that she has constitutional experts looking at the issue and that she will decide likely by February if she will pursue another term.
