While i suspected a bias against a candidate named Yvonne, all i can say just looking at my notes below is that there's plenty of split tickets.
Tempted to crunch more numbers. I'm sure there's a factor out there that points to the statistical influence of incumbency.

* Mark beat Yvonne.
** Beth beat Anthony.
† Steve beat Jenna -- and honestly, Steve Troxler has been Ag Commissioner for years and i find he's done a respectable job in general, and seems to have been sensible about Covid. I understand why a Dem might choose to vote for a R in this case. Jenna
†† Josh beat Jessica
‡ Elaine beat EC
