Today's Cincinnati Enquirer quotes eleven non-voters from Cincinnati, most of whom did not find anything on the ballot compelling enough to get to the polls.
Some, a few, simply did not have the time after working a long day or shift and then having a commitment at the end of the day - family, appointment, etc. Here's where making voting by mail easier would help. It is fairly easy at present, I believe, but takes a little planning ahead, and apparently, some or many cannot or so not do that re voting.
One woman expressed that "blacks", her words, did not see gains and so, apparently, she did not see the value in voting. I would have pointed out to that woman that City council members represent both black and white citizens and that black council members went from five to four as a result of this election, so more black voters might have influenced that number.
We all know that older white voters will come out, and in SW Ohio, the majority are Republican. So Dems need to work harder to get out the vote in non-presidential years.
