Scottsdale Mayor Jim Lane closed the door on a long-rumored candidacy for state treasurer, saying he made a commitment to the voters who re-elected him last year.

State Treasurer Doug Ducey filed an exploratory committee for the 2014 governor’s race, taking the first steps toward his widely expected candidacy for the state’s highest office.

Campaign cash may come pouring into some of Arizona’s top races next year thanks to a new law allowing candidates to raise far more money.

The biggest name in Democratic politics in Arizona won’t jump into the fray for the 2014 governor’s race. Former Surgeon General Richard Carmona told KPNX-TV (Channel 12) reporter Brahm Resnik in a Sunday interview that he won’t seek the Democratic nomination for governor.

Fred DuVal’s gubernatorial campaign is semi-official after filing an exploratory committee today, making him the first Democrat to test the waters for the state’s top office in 2014.

DuVal, a former regent, former Clinton White House aide and longtime Democratic operative, said he expects to file his campaign committee with the Secretary of State’s Office by the end of February.
