I typically enter a street address, get the ballot names here: https://ballotpedia.org/Ohio_elections,_2018
Then i proceed to visit every candidates page just to read what they feel most strongly, about while researching further into topics if I need to try and find more info...like does "Dettelbach or Yost support issue 1?" ect.
Obviously the candidates pages are all rainbows and glitter, but you can kind of see what they seem to feel strongly about. Reading articles and such is tough...always someone elses opinion in the end it seems.
