More than two weeks after Sen. John Kerry conceded defeat and urged national unity, the Internet is still ablaze with accusations and theories about alleged voting irregularities, rigged equipment, machines that counted backward, machines that stopped counting, and all manner of possible mishap from incompetence to corruption and outright fraud. Four in five Americans believe the election was conducted fairly, including two-thirds of all Democrats, according to a poll released Wednesday by Harris Interative. But 16 percent are suspicious of the outcome, with more than one in four Democrats saying it was tilted, deliberately or not, toward President Bush. While Kerry and his top aides have not challenged Bush's re-election, some prominent Democrats are joining the fray. Two days after Kerry's concession, three Democratic members of the House Judiciary Committee wrote the head of the Government Accountability Office demanding an urgent investigation of the election. The congressmen cited reports from Ohio, Florida, North Carolina and other states about voting machines that had lost votes, voting machines that had failed to count votes, voting machines that had given extra votes to Bush. But that's tame compared to some of the inflammatory rhetoric on the Internet. A host of Web sites and bloggers are alleging a conspiracy of massive proportions to ensure Bush's victory. A typical site is "Stolen Election 2004", whose home page begins: "In Election 2000, the Bush regime stole the election and got away with it. Now, in Election 2004, there is new evidence that Bush and the Republicans have stolen the 2004 election by electronic voting fraud in states with E-Voting without paper trails, scrubbing the voter rolls of Democratic voters, and destruction of paper ballots in heavily Democratic areas." The site then invites visitors to "post any evidence of election fraud at our new Stolen Election 2004 Blog," and it provides electronic links to other Web sites making similar allegations.
