Arizona Senate Majority Leader John McComish says he won't run for re-election but instead will seek a Justice of the Peace post in the November election.

McComish is a Republican from the south Phoenix suburb of Ahwatukee in his ninth year in the Legislature. He is outranked in Senate only by President Andy Biggs.

McComish is endorsing Republican Rep. Jeff Dial for his old seat.

Both McComish and Dial are considered moderates and supported Gov. Jan Brewer's effort to expand Medicaid last year.

He said nearly 10 years in the Legislature is a long time, and with Justice of the Peace terms lasting four years, he needed to make the move now. He will seek the Kyrene Justice Court seat representing Ahwatukee and parts of Tempe and Chandler.
