You may need to do some homework before deciding who to pick from this long list of 20 candidates. You may either look at this AJC guide , or take the shortcut from either parties. I found this shortcut from DP. But I'm unable to find a similar shortcut from RP, maybe they mean to keep the "incumbent".
I find this AJC article very helpful, in case you need some insight before going to the poll. For these 3 non-partisan issues, my choice are all "YES".
