The charges [against Kerry by the Bush campaign] were all tough, serious -- and wrong, or at least highly misleading. Kerry did not question the war on terrorism, has proposed repealing tax cuts only for those earning more than $200,000, supports wiretaps, has not endorsed a 50-cent gasoline tax increase in 10 years, and continues to support the education changes, albeit with modifications.

Scholars and political strategists say the ferocious Bush assault on Kerry this spring has been extraordinary, both for the volume of attacks and for the liberties the president and his campaign have taken with the facts. Though stretching the truth is hardly new in a political campaign, they say the volume of negative charges is unprecedented -- both in speeches and in advertising.

Three-quarters of the ads aired by Bush's campaign have been attacks on Kerry. Bush so far has aired 49,050 negative ads in the top 100 markets, or 75 percent of his advertising. Kerry has run 13,336 negative ads -- or 27 percent of his total. The figures were compiled by The Washington Post using data from the Campaign Media Analysis Group of the top 100 U.S. markets. Both campaigns said the figures are accurate.

Incumbent presidents often prefer to run on their records in office, juxtaposing upbeat messages with negative shots at their opponents, as Bill Clinton did in 1996.

Scott Reed, who ran Robert J. Dole's presidential campaign that year, said the Bush campaign has little choice but to deliver a constant stream of such negative charges. With low poll numbers and a volatile situation in Iraq, Bush has more hope of tarnishing Kerry's image than promoting his own.

"The Bush campaign is faced with the hard, true fact that they have to keep their boot on his neck and define him on their terms," Reed said. That might risk alienating some moderate voters or depressing turnout, "but they don't have a choice," he said.
