Former U.S. Rep. Tom Tancredo has become the latest Republican to announce plans to challenge Democratic Gov. John Hickenlooper.
Tancredo said Thursday on radio station KHOW the last straw was a decision by Hickenlooper to delay the execution of convicted murderer of Nathan Dunlap, who was convicted of killing four people in 1993. Tancredo says he is also upset with Hickenlooper's approval of sweeping gun legislation this year, including a law limiting the size of ammunition magazines
Steve Laffey, a onetime Republican U.S. Senate candidate in Rhode Island, announced Tuesday he's running for governor of Colorado.
Secretary of State Scott Gessler has also expressed interest.
