Jim Barnett is throwing his stethoscope into the ring.
The 63-year-old doctor and former state senator is running for the Republican nomination for governor.
Barnett, who represented an Emporia-centered district in the Kansas Senate for a decade, won the 2006 GOP primary over a relatively weak field but lost in a landslide to incumbent Democratic Gov. Kathleen Sebelius in the general election.
Four years later he came up short in a race against Tim Huelskamp for the Republican nomination in the 1st Congressional District.
