The Boston Globe has an excellent article, accompanied by one of the best graphics I've seen so far, regarding nationwide voting errors.
I'm a scientist. I like hard numbers and statistics. I don't like wild speculation, so I won't engage in that here, because you can't simply look at a map and say "FRAUD!" or even "SUPPRESSION!" without knowing much more about that specific state.
Anyway, look below the fold for the graphic and excerpts from the article.
Voting errors tallied nationwide
More than 4,000 votes vanished without a trace into a computer's overloaded memory in one North Carolina county, and about a hundred paper ballots were thrown out by mistake in another. In Texas, a county needed help from a laboratory in Canada to unlock the memory of a touch-screen machine and unearth five dozen votes.
In other places, machine undercounting or overcounting of votes was a problem. Several thousand votes were mistakenly double-counted in North Carolina, Ohio, Nebraska, and Washington state. Some votes in other areas were at first credited to the wrong candidates, with one Indiana county, by some quirk, misallocating several hundred votes for Democrats to Libertarians. In Florida, some machines temporarily indicated votes intended for challenger John F. Kerry were for President Bush, and vice versa.
In the month since the election, serious instances of voting machine problems or human errors in ballot counts have been documented in at least a dozen states, each involving from scores of ballots to as many as 12,000 votes, as in a North Carolina county. On Election Day, or in later reconciling tallies of ballots and voters, local officials discovered problems and corrected final counts. In some cases, the changes altered the outcomes of local races. But in North Carolina, the problems were so serious that the state may hold a rare second vote, redoing a contest for state agriculture commissioner decided by fewer votes than the number of ballots lost.
After the disputed vote in Florida four years ago, Congress passed the Help America Vote Act of 2002 and authorized $4 billion so states could create central computerized voter lists and replace outdated voting systems such as punchcards by 2006. But many states have not completed the overhaul, and this year's election unearthed enough problems -- both with older technologies and newer electronic touch-screens -- that two federal agencies plan unprecedented nationwide inquiries. The investigations by the Government Accountability Office and US Election Assistance Commission will begin early next year and be completed by mid-2005, at the earliest.
In addition, minor presidential candidates requested recounts in four states -- a partial one completed yesterday in New Hampshire, and statewide in Ohio, New Mexico, and Nevada.
None of the recounts or inquiries is expected to affect the results of the presidential election, which Bush won by more than 3.3 million votes.
