A former Idaho legislator from Pocatello, Evan Frasure, is running as a Republican in the ever-more-crowded 2014 secretary of state primary.
The Idaho State Journal reports Friday Frasure plans to make a formal announcement next week.
Frasure says he believes it's the right time for somebody from eastern Idaho to fill the post.
Already, two southwestern Idaho people have joined the GOP primary race: Rep. Lawerence Denney of Midvale, and deputy Ada County Clerk Phil McGrane.
Frasure served 12 years in the Legislature until departing in 2002 to run for secretary of state against the eventual winner, Ben Ysursa.
Ysursa is retiring after three terms.
Frasure is a teacher and was a member of the redistricting committee in 2011 that failed to draw up new election boundaries for Idaho.
