The most fundamental of democratic processes has become more barrier-filled and error-prone than at anytime since Florida’s 2000 election, when voter list purges, flawed voting technology and a partisan U.S. Supreme Court majority ended a statewide recount and installed George W. Bush as president. This fall’s potential problems begin with a new generation of voter suppression laws and aging voting machines in a handful of presidential battleground states. And other important factors are in play, such as election officials curtailing voting options due to fiscal constraints, the increasing age of poll workers—volunteers averaging in their 70s—who must referee an ever more complex process, and the likelihood that close races will end up in post-Election Day legal fights. Voters tell academics they want consistency in voting. Yet emerging trends are poised to upend that hope in many states. This year’s big questions are: where will the meltdown—or meltdowns—occur, what will go wrong, on what scale, and, when it comes to computer failures or tampering, will we even know about it?
