The state’s 19,000 electronic voting machines are running smoothly and will be able to handle any influx of ballots come Election Day, Maryland Elections Administrator Linda Lamone said Wednesday.

That number of machines represents an 18 percent increase over the past presidential election compared to a 9 percent increase in voter registration this year, Lamone said. The state has voting machines on reserve to replace any that malfunction, and each has been tested by outside contractors who have had criminal background checks.
