The demise of the CO GOP began under the Bush presidency. Trump obviously didn't help, but they badly underperformed in the Obama years as well (even in 2010 and 2014). This is what migration can do to a state. I don't think it is comparable with what happened in VA, though.
Anyway, the gubernatorial race is definitely Leans or maybe Likely D, but it would have been that way even if Clinton had won the presidency.
Sad. Many children of those Dole voters are liberals. And remember, Dole's win wasn't even that impressive, his margin of victory was smaller than Nader's performance.
I think it is quite impressive when you consider that Dole lost Arizona and Nevada in the same election, that Perot got 7% of the vote and that Clinton was obsessed with winning the state again.
