There were not too many surprised last night, I think everyone expected Braun to get the nomination for governor. I'm not sure either would have been a surprise in Spartz v Goodrich, so Spartz's percentage may have been a bit higher than I would have thought. Statewide, Haley won 21% of the vote. In Hamilton County it was 33%.
Since Biden isn't opposed, it isn't as easy to figure out the number of non-Biden Democrats. Michigan and Minnesota indicated there might be a hefty number.
It could be that Democrats crossed over to vote for Haley. In which case that means nothing. But it is hard to get people to go out and vote in a primary, period. So that 33%, or even 21%, seems high just to be that. And Haley is getting about 20% in closed primaries. So the fall election may well be determined by that 20%. They didn't want Trump enough to vote for someone who hasn't been in the race for months, will they go ahead and vote Trump in the fall.
You can see in the Wiki that before last night, Trump is averaging 75%.

Pennsylvania 83
I am not pointing this out to say Biden will win as I don't think he will (the Republicans still have a structural advantage in the Electoral College). I am saying this is going to be an election determined by who is willing to hold their nose and vote. I once heard Johnny Carson use the phrase, "The evil of two lessors". That is where we are.
