But whether Donald Trump will secure the Republican nomination is secondary to a more serious quandary: whether the nation's voting machines will hold up when Americans head to the polls in 2016. 

Nearly every state is using electronic touchscreen and optical-scan voting systems that are at least a decade old, according to a report by the Brennan Center for Justice at New York University School of Law (.pdf). Beyond the fact the machines are technologically antiquated, after years of wear and tear, states are reporting increasing problems with degrading touchscreens, worn-out modems for transmitting election results, and failing motherboards and memory cards.

States using machines that are at least 15 years old include Florida, Kentucky, Massachusetts, New Hampshire, Texas, Virginia, and Washington, which means they are far behind even a casual tech user in keeping pace with technological advancements.
