MESA, Ariz. (AP) — Gov. Jan Brewer has delivered a crucial and sought-after endorsement in the Republican governor's race.

The governor endorsed former Mesa Mayor Scott Smith, quickly revitalizing his candidacy in the six-person race.

Brewer has been courted by the top candidates as they look to break away from the pack in a tight race. She said Thursday at the Chicago Cubs spring training park that Smith shares her values on Medicaid expansion, Common Core, the economy and border.

Brewer has made a name for herself nationally with her tough stances on immigration — an issue that has dominated the race since the surge of immigrant children and families from Central America. Smith is considered the most moderate of the candidates on the issue, however.

The primary is Aug. 26.
