These numbers are similar to provisional ballot usage in 2016, when 154,965 provisional ballots were cast across the state, of which 85% were counted. In 2012, 208,084 provisional ballots were cast and 83% counted.
“The No. 1 reason (they are rejected) is that they were not registered to vote," said Aaron Ockerman, executive director of the Ohio Association of Election Officials. "But some of them are not counted because they were missing information on the envelope and never got it to the board of elections, typically some piece of identification.”
Montgomery County Board of Elections Deputy Director Steve Harsman said historically 10% to 13% of provisional ballots there are invalid.
Voters can be asked to vote provisional ballots for several reasons, including their names not appearing on the official poll list for their precinct.
The number of provisional ballots cast this year is “very low for a presidential election,” Harsman said.
Another roughly 6,700 absentee ballots requested by Montgomery County voters but not yet received will be counted if they were postmarked by Nov. 2 and are received within 10 days. That number in Greene, Miami and Warren counties is 2,271, 942 and 2,159, respectively.
Harsman said historically only about 500 to 1,000 absentee ballots are received after Election Day in Montgomery County.
The state doesn’t keep historical data on how often ballots arrive after Election Day. But in 2016 there were 80,014 ballots sent to voters that were never returned, according to data from the Ohio Secretary of State. That included 3,317 in Montgomery County.
