"Compared to counties with paper ballots, counties with electronic voting machines were significantly more likely to show increases in support for President Bush between 2000 and 2004. This effect cannot be explained by differences between counties in income, number of voters, change in voter turnout, or size of Hispanic/Latino population. In Broward County alone, President Bush appears to have received approximately 72,000 excess votes. We can be 99.9% sure that these effects are not attributable to chance."

This is Florida only. You do the math. The interesting part is not that such things happened, but that there is so much silence around them.
