Fundamentally a primary helps every candidate besides Linda. She has the best name recognition and has raised the most money (with the potential to raise more) a single round helps her significantly more than anyone else. Turnout in general in this race is going to be low so name recognition is going to be helpful, she can take full advantage of her money advantage.
If you are any other candidate your best bet is to get into a one on one round with Linda where those advantages she has are mitigated.
You can force a primary with 5 candidates, this includes write-in candidates so if you want to force a second round it isn't that hard. You just need to get one or two folks to run as write-in candidates and you have a second round.
I fully expect that we will have two rounds.
