A new Ohio program intended to make voting easier has the potential to keep the presidential election in doubt until late November if the national outcome hinges on the state’s 18 electoral votes.Under Secretary of State Jon Husted’s initiative to send absentee ballot applications to nearly 7 million registered voters across Ohio, more than 800,000 people so far have asked for but not yet completed an absentee ballot for the Nov. 6 election.Anyone who does not return an absentee ballot, deciding instead to vote at the polls, will be required to cast a provisional ballot. That’s so officials may verify that they did not vote absentee and also show up at the polls.
