Jaime McMillan sounds like a strong candidate (for Immigration Reform, Anti-Drug War) for Colorado, hopefully he makes it out of the primary.
He'd have to get his name recognition up in order to make it through the primary. Right now, he doesn't even have a Wikipedia article. 
He does sound like a better fit for the state than the other declared candidates, though, from what you've said.
He might have a problem in the primary though, as he's pro-choice
I'd say this is still Lean/Likely D, especially since a loon is likely to take the nod (I wouldn't be surprised if Ken Buck wins this outright).
As much as Colorado has shifted, we should still be able to obtain someone who is at least nominally Pro-Life if a victory is possible here. Remember, base turnout would still matter here and that Colorado Springs crowd has to have at least something to sink their teeth into.
I still don't think Buck can win Jeffco, so the best chance is also not him obviously.
