Senators John McCain and Jon Kyl, Republicans of Arizona, have endorsed Gov. Jan Brewer (R., Ariz.) in her gubernatorial primary. “There has been no stronger defender of the State of Arizona than Governor Jan Brewer,” McCain said in a statement. “From border security to health care to job creation, Governor Brewer has consistently stood up for our state. Governor Brewer continues to lead the fight against the Obama administration’s frivolous lawsuit against Arizona’s immigration law. Governor Brewer is clearly the right leader to guide Arizona through these challenging times, and I am proud to support her.”

Brewer’s primary is on August 24. Here’s the Rasmussen take:

[Earlier in the year,] Brewer’s unpopularity, largely over her handling of the state’s budget problems, prompted several other Republicans to challenge her for the gubernatorial nomination. Brewer was struggling until she signaled her opposition to the health care law and then began to move ahead. Since signing the immigration law, however, her support has soared to 61%. Barring unforeseen developments, she is expected to easily win the August 24 primary contest.

For months, Brewer’s main foe was Dean Martin, the state treasurer. He bowed out of the race last week.
