I had a dinner with a "enlightened" medical Doctor months ago and although he voted for Trump he said he and many of his Doctor friends will support Haley. Although emphatic and believing his own reasons, he and all his fellow GOP leaning Doctors are most likely voting Trump now, they are not that stupid.
My point was, multi-candidate primaries often define “winning” (as they did constantly with Romney) has having 25%-30% support - which is fine if the candidate is everyone else’s second choice.
And let me inbefore everyone points out a lot of Democrats in NH voted for Haley - true but a minor factor in my heavily Republican town, Trump + Haley got 2100 votes and Biden got 778 write-ins, which is about the party registration breakdown. Of Haley’s 1000 votes, most of them had to be from registered Republicans unless you believe a lot of Republicans wrote in Biden.
