Crnich said almost 200 ballots were inexplicably dropped from the final election results. The error did not change the outcome of any of the races, Crnich said.

Dan Wallach, associate professor of computer science at Rice University, also recommended that Colorado use paper ballots counted on scanning machines.
"Hand-marked paper ballots that are machine-scanned are the best technology that's on the market today," Wallach testified at the state Election Reform Commission meeting at the state Capitol.

Rice University professor Dan Wallach, a nationally recognized voting-machine expert, said paper ballots counted by scanning machines are much more resistant to widespread election fraud.
"In terms of the systems that are available today, hand-marked paper ballots counted by scanners are the best technology," Wallach said.

But the process of voting in Tuesday’s presidential election — which may set a record for turnout — was relatively smooth, with no reports of catastrophic failures that kept large numbers of people from casting a ballot.
