Lieutenant Gov. Brad Little is running again in 2014, hoping to secure a second elected term.
Little made the announcement Wednesday in Emmett, his hometown about 40 miles northwest of Boise.
The 59-year-old Republican rancher and businessman was appointed in 2009 by Gov. C.L. "Butch" Otter after former Lt. Gov. Jim Risch's U.S. Senate election. He was re-elected in 2010.
With Otter planning to seek a third term, Little appears content to remain in the part-time, $35,100-per-year job as the governor's fill-in.
However, Little has said he's interested in running for governor, should Otter no longer vie for the post.
To that end, he's been trying to elevate his statewide profile, acting as Idaho's economic liaison on trade missions and sending out a weekly calendar advising media of his whereabouts.
