There is only one winner here, all the rest are losers.
...but but but it was HISTORIC!
One comment about “winning” a primary (n/a to current situation).
“Winning” a 5-way nominating contest with 30% of the vote (looking at Mitt Romney 2012) is not winning at all if 70% of the voters don’t want you.
The presumption that voters for the loser will support the winner is obsolete.
In my town, Trump beat Haley 1100-1000, but not one of those 1000 Haley voters will vote for Trump in November.
