"In big counties such as ours, retrofitting these machines can cost hundreds of thousands of dollars. But the alternative is worse: potentially disfranchising thousands of voters. That's unacceptable, particularly after the 2000 presidential election. In Miami-Dade County, for example, a post-election analysis of 31 precincts in that election showed that 8.2 percent fewer votes were counted than the number of voter signatures recorded in those precincts. These kinds of results erode trust in the fairness of elections."
