New York City’s Board of Elections has complained for weeks that the electronic voting machines first used in 2010 cannot handle the city’s tight primary elections schedule. But one solution, endorsed by the board and under consideration in Albany, seems absurd. The board and the State Legislature are talking about scrapping the new machines and replacing them with the old metal clunkers, with their creaky levers, that went out of production more than 30 years ago. The issue arises because the primary elections are set for Sept. 10. State law requires a runoff two weeks later if no one receives more than 40 percent of the vote in citywide races, which seems likely with at least five competitive candidates in the Democratic mayoral race. But the board claims it needs more than two weeks to reset the electronic machines and print new ballots.
