Yes, it's the Nazi comparison. Bear with me.

I'm aware that invoking Godwin's Law at this time needs extreme justification, but I think there's one angle that I haven't seen anyone pick up on yet. Namely, the choice between Hindenburg and Hitler in 1933 was a much more forgivable situation for the electorate to make a grievous mistake on than what has just happened. Most of the populace had a lack of any real media access, the economic situation was truly dire with starvation only a stone's throw away for many, the whole world was far less culturally tolerant and the trauma and injustice of recent history hung heavy over it all. On top of that, one side employed actual widespread violence to bend opinion.
Yet Hitler didn't actually win the election. Put that in your pipe and smoke it.
