This guy appears to be serious:
Colorado Republican gubernatorial candidate Dan Maes knows you might think bicycles and bicycle riding are harmless, but beware: "That's exactly the attitude they want you to have."
The Denver Post reports that Maes, a Tea Party friendly candidate facing former Rep. Scott McInnis in the August 10 Republican primary, has come out against a public bicycle program run by the city of Denver. Denver's mayor, John Hickenlooper, is the presumptive Democratic nominee, and a cycling supporter.
"This is all very well-disguised, but it will be exposed," Maes said at a small campaign rally last week, according to the Post. "These aren't just warm, fuzzy ideas from the mayor. These are very specific strategies that are dictated to us by this United Nations program that mayors have signed on to."
Find me a position on the left that's this ridiculous. And good luck because there isn't one. Maes is a crackpot -- and he's not an exception.
