If Colorado Republican candidate Ken Buck is elected to the United States Senate, he will add to the growing list of climate change deniers in the upper chamber.

Buck, who is in a tight battle with Colorado Sen. Michael Bennet, explained his beliefs while campaigning in Loveland, Colo.

Buck, who is the Weld County district attorney and is backed by the Tea Party, invited Oklahoma Sen. Jim Inhofe, a vocal climate denier, to a recent campaign event.

A Denver Post blog provides an interesting account of the rally. “Sen. Inhofe was the first person to stand up and say this global warming is the greatest hoax that has been perpetrated … the evidence just keeps supporting his view, and more and more people's view, of what’s going on,” said Buck, according to several reports.

Buck’s campaign reps aren’t backing down from those comments, according to the Post report, which quotes Buck spokesperson Owen Loftus saying, “The Obama EPA regulations would put Coloradans out of work and drive up energy costs on consumers at a time that we can least afford it.”

Buck’s team is trying to make the economic argument for denying climate change, a clear contradiction to a report from the National Conference of State Legislatures (NCSL), which points out that “Colorado could be affected by more than $1 billion in losses due to impacts on tourism, forestry, water resources and human health as a result of climate change.”

Maybe the NCSL is in on the “climate hoax,” or even more concerning, they are a bunch of Nazis?  (And in case you haven't had a cup of coffee this morning, that's a joke. The National Conference of State Legislatures or NCSL has offered several reports on how states must deal with climate change in the absence of federal rules.) 

Generally speaking, the Nazi card isn't part of the climate discussion unless one of the participants is Buck’s new pal, Inhofe. (Inhofe once claimed that the Kyoto Protocol “would deal a powerful blow on the whole of humanity — similar to the one humanity experienced when Nazism and communism flourished.” The Oklahoma Republican has several other interesting quotes.)

As for Buck, bringing the Oklahoma senator with him on the campaign trail is an odd choice considering he is already digging out from some controversial comments made a few days ago. On NBC’s "Meet the Press," Buck claimed that homosexuality is a choice and compared its cause to the causes of alcoholism.

Almost all polls show the Buck-Bennet race is a toss-up right now. It will be interesting to see how the Inhofe climate-bashing tactic plays in Colorado and if the "Meet the Press" incident makes a difference.

You've got to love election year politics.
