Every county has their own races. Sometimes every district IN the county has their own races. Can’t have a statewide uniform ballot with local races being different everywhere.
I’ve seen the ballot. It has 3 columns, you start on the left and read down like with any newspaper, first you get the instructions, and then the votes start.
If you were stupid, you skipped the instructions, and then assumed that the ballot marking started in the 2nd column, and continued into the 3rd column, and then you completely forgot that you were supposed to vote for a senator.
In most counties there are local issues: school bonds, local judges, county offices. A uniform statewide ballot will not work, or at least not the way we do elections now.
What might work is one ballot for statewide races, and a separate one for county issues. But then each person has to vote two ballots, and I am pretty convinced that a significant number will not understand this and will only vote one.
