I don't think Hillary will be on any kind of ice in 2020? But that is an interesting observation. Minnesota along with Maine, New Hampshire, and Colorado (and maybe Nevada but I'd doubt it) are all states Trump could flip in a close election.
Colorado does not warrant inclusion on that list. Trump is a horrible fit for the state, and I'm betting he's already starting to piss his weed-friendly supporters there off.
Hillary was polling underwater in Colorado in early 2016 against every GOP candidate. But Trump's comments made her rebound in that state.
