Maryland Comptroller Peter Franchot, who had considered running for governor in 2014, told supporters Tuesday he will bow out of that contest to seek another term as comptroller instead.

Franchot, a Democrat, has frequently been at odds with Gov. Martin O'Malley's administration. His decision not to run comes amid speculation that Democrats will have a crowded and potentially messy gubernatorial primary in 2014.

"This is a decision that I have made after a great deal of personal reflection," Franchot, 65, said in a message posted on his website Tuesday. "It is no secret that in recent months, I have given thought to running for governor. I am humbled by the extraordinary support that my prospective campaign received in every corner of our state, and I am now more convinced than ever that there is a shared desire among Marylanders -- irrespective of ideology or party affiliation -- for an honest conversation of the fiscal and economic challenges that still lie ahead."
