Is CO a Democratic state?

[Virginiá]

Republicans can still win it if they put up the right candidate, but every year that passes the state appears to be getting more Democratic. However, various issues in the future could change this. At the state level, the trend is pretty heavy Democratic since the early 2000s-now and with minority growth, I'd expect this to slip out of reach for Republicans sometime in the 2020s, assuming current trends continue uninterrupted.

What are we defining as a Democratic state?

I assume a mostly Democratic state government and Democratic at the federal level as well (obviously not 100% Democratic all the time for all federal races, though).

If that's the foundation of 'Democratic state', then Colorado has some strong pro-Democratic trends but it's not quite there yet.
