Ohio's Electoral College votes are cast for the winner of the state, not per district [1]. Of course you should vote for Biden (or whoever the ultimate candidate against Trump will be)!
Thank you, this is the kind of info I was looking for. If county/district mattered. So all of Ohio is Talley'd up and all votes from the whole state are in the same pool?
Thats right. Your vote counts the same as one in Cincinnati or Cleveland or Athens etc. then the whole state goes one way or another. Thats why turnout is so important!
Also there might be down ballot races you vote for that move the needle. Everyone forgets about local elections but they actually matter way more to your life on a day to day basis.
All states except Maine and Nebraska tally votes cast statewide and allocate all electoral votes from that state to the winner. Specific concentrations of voters in those states aren't factored into the allocation.
