I wouldn't count Kris Kobach out. Yes, Brownback did a crappy job, but Kobach is a Republican and not Brownback.
In all seriousness though, besides Kobach's failed voter fraud thing is there any other reason why Kansas would vote against him if he won the primary (something related to him, not like "D wave year")
He seemed pretty ready to jump ship and work for Trump instead of focusing on Kansas when Trump was forming his cabinet.
I can see that being a problem, but so many politicians have done that in the past. Would that really matter, especially in Kansas?
