This one is more (as in: exactly) pertinent to @Hoosier's question. https://www.statista.com/statistics/1135833/us-presidential-elections-current-streak-by-state/ MN is up there but is as already mentioned outranked by DC and also a gaggle of Western states that have voted (R) since 1968.

I found this fairly easily: https://www.statista.com/statistics/1136235/us-presidential-elections-longest-streak-by-state/ According to it, the current winner is DC, which has voted (D) since 1964.

All we are is dust in the wind.

Everything is ultimately a question of when and not if. Good news is that we are only here for a brief second and likely won't see any of it happen.

It would be shocking if Trump breaks 20% among black voters. I don't expect that to realistically happen. But if he picks up a few percent or so from last time, then it could cancel out whatever he loses from people not wanting to vote for a criminal, etc
