Sen. Jack Harper of Surprise has filed an exploratory committee and is considering a run for Arizona secretary of state in 2010. 

"The position (becomes) open in 2010, and that is something that interests me," Harper said. "I have a passion for free and fair elections, and so I will be exploring whether or not there is support for me to run for that office."

Secretary of State Jan Brewer is expected to run for governor in 2010.

Harper, a Republican who serves as chairman of the Senate Government Committee, was re-elected on Nov. 4 by a margin of 60 percent to 40 percent over Democrat challenger Robert Boehlke.
