1. Put up a sign at the old place with directions on where to go.
2.Put up a sign in the new place.
3. If this was done on purpose to suppress voting then having a way to catch somebody removing the signs you put up will lead to catching the RATS responsible.
I have worked as a Poll Worker for every election in my CA district over the past year because I felt something was wrong.
On off year elections, like most counties, Election Board, the Los Angeles County Board of Elections, consolidates Polling locations simply because LESS people tend to vote in these elections and it is harder to get VOLUNTEERS to work the elections.
This could be the case in your Ohio district but it is up to us, the people to work the polls and read the materials that are sent out PRIOR to the election.
Most importantly, you are Voting! That is the most important fact in your post and I salute you for exercising your right as a citizen!
