I don't think he will - I think he will probably win the GOP nomination, as he's got a lot of Tea Party support, but I can't see him beating Hickenlooper unless something really weird happens. Not that weird things don't happen all the time in politics. But Colorado is split pretty evenly between Dems, GOP, and ferociously independent, and I think the independent vote (as well as the intelligent wing of the GOP, who will acknowledge that at least the Dem guy is a successful businessman and did a good job as Denver mayor) will swing things toward Hickenlooper.
