DENVER (AP) — Colorado Democratic Gov. John Hickenlooper said Friday he was dumbfounded by a television ad from Republican challenger Bob Beauprez referencing the death of state Corrections Director Tom Clements in an effort to criticize Hickenlooper's public-safety record. In their eighth and final gubernatorial debate, Beauprez said it was not his intent to politicize Clements' death or offend his widow, who asked the campaign to stop mentioning her husband's death. Clements was trying to reduce the use of solitary confinement, and after his death, his department implemented a policy to stop placing mentally ill inmates in solitary. The matter of land-disputes between residents and energy companies over hydraulic fracturing, or fracking, also came up, with Hickenlooper arguing that a commission he assembled to study the issue is a path to compromise.
