75k turning out for a Democratic in DC is not unexpected. Trump filling MSG in New York, a liberal stronghold is more impressive.

 I partially agree.  Trump can bring out humans that typically would not go to an event.  This is my opinion for anyone uncapable of understanding what an opinion is.

 I do notice however a multitude of humans that are attending opposite-side events, just to see what's going on there.  There has been a ton of online promotion for that this year.
