He's also the Vice Chairman of the DGA. He won't run for President though. He's in a similar situation to O'Malley where under Hick's leadership, the CO Dems faced huge setbacks this year with Udall and losing the state legislature.
There's also the fact to that the Clinton's helped campaign for Hickenlooper this year, and Hick owes Hillary his patronage in 2016 when she runs.
I think he could make a very strong VP pick though. Hillary needs a male running mate, one who's preferably young, Hillary isn't well-liked in Colorado, and Hick simply has a great resume of being able to survive 2 GOP waves in a swing state. I could definitely see Hillary picking him as her running mate.
Hick is definitely a survivor and would help a Dem ticket at the bottom immeasurably.
