Colorado is something like the 3rd most college-educated state in the country, and the GOP has collapsed with college-educated voters in the Trump era.
I've said it before, but they really can't afford further slippage with this group. As the decade goes on, millennials and Gen Z will comprise a larger share of the electorate, and they are much more college-educated than older generations.
Yeah this.
And it's really problematic how far they've slipped with college educated voters not just for the reasons you gave but also because college educated voters vote in off years, down ballot races, etc. So now the GOP is in a situation where there are not only more Democrats than Republicans nationally but the Dems at this point might have more reliable voters than they do. Republicans do have old people but that's not enough.
