November 1920

In the age of ballot-box stuffing, the mechanical voting machine promised indisputably accurate election tallies. Sound familiar?

November 1920

“When this drink dispenser is placed in a busy locality, as much as four hundred dollars has been earned by it in a single day.”

“Plot and plan, scheme and engineer as he may, the crooked ward-heeler cannot discover a way of cheating the machine,” PopSci wrote in 1920, urging the widespread adoption of mechanized voting as an antidote to Tammany Hallstyle election fraud. The gear-and-lever voting machine seemed to ensure a fair and scientific tally. Although it had debuted two decades before we featured it on our cover, in 1920 it was used in only 17 states. By the 1960s the machine predominated in U.S. elections. But by the ’80s, it had fallen from favor because of serious shortcomings: It lacked a paper trail, had in fact proved to be susceptible to tampering, and broke frequently. Now, as officials rush to install electronic voting equipment for this month’s presidential election, experts warn that e-voting machines may possess the same drawbacks as their mech-anical predecessors. “Wow,” UC Berkeley computer security an-alyst David Wagner says of PopSci’s early enthusiasm. “Replace the word ‘mechanical’ with ‘electronic,’ and we’re right back to today.”
