Looks like Colorado really is New New Mexico.
Not really, CO would have been perfectly winnable with just about any other Republican candidate.
I honestly have no clue why Trump had been polling within 5% of Hillary in the first place. Everything about that state looks like a disaster for him. The GOP base consists of:
1. Educated, wealthy elites.
2. The religious right.
3. The military establishment.
All I can think is that Hillary Clinton's unpopularity with both the right and the left (which is basically a transplanted Cascadia) drove voters towards either considering staying home, voting Johnson, or holding their nose and voting Trump.
The right-wing intelligentsia (pro-establishment, pro-globalism, neo-con) has to be the weakest part of the Republican coalition for Trump.
It looks like the state is finally drifting back to what I would expect from them given the fundamentals.
