The disputed election of 2000 left a lasting scar on the nation's psyche. A recent Zogby poll found that even in red states, which voted for George W. Bush, 32 percent of the public believes that the election was stolen. In blue states, the fraction is 44 percent.
Now imagine this: in November the candidate trailing in the polls wins an upset victory — but all of the districts where he does much better than expected use touch-screen voting machines. Meanwhile, leaked internal e-mail from the companies that make these machines suggests widespread error, and possibly fraud. What would this do to the nation?
Unfortunately, this story is completely plausible. (In fact, you can tell a similar story about some of the results in the 2002 midterm elections, especially in Georgia.) Fortune magazine rightly declared paperless voting the worst technology of 2003, but it's not just a bad technology — it's a threat to the republic.
