After the pandemonium over dimpled and pregnant chads in the 2000 election, nearly everyone agreed it was time to rethink old vote-counting ways. But the stampede to touch-screen voting was not inevitable.
Another, demonstrably more reliable technology was already on the rise: optical scan voting, introduced in some parts of the country in the late 1970's. By the 2000 election, optical scanning - which involves marking a paper ballot that is ultimately read and counted by a computer - had overtaken all other voting methods as the most common way to vote in the United States. This year, optical scan systems will be used in more than 45 percent of all counties, according to Election Data Services, a political consulting firm in Washington.
After the 2000 election, a study by the Voting Technology Project, a joint effort by the California Institute of Technology and the Massachusetts Institute of Technology, took a hard look at the nation's voting systems. Using a measure of what they called "residual votes" - overcounting, undercounting or not counting votes for any reason - researchers found that two existing voting methods had produced relatively low error rates in the last four presidential elections: old-fashioned hand-counted paper ballots and optical scan systems....

But election officials who decided to change systems overwhelmingly went for the touch screens. Compared with about 13 percent of registered voters in 2000, this year roughly 30 percent of those registered will be asked to vote on electronic systems. Optical scan systems grew as well, although at a much slower pace: from about 30 percent of registered voters in 2000 to just under 35 percent this year, according to Election Data Services....
