Next time you hear a Republican toss out the canard that they're tired of seeing/hearing negative attack ads, educate them to the fact that their side is far more guilty of this sleazy tactic. Example, this item in today's Washington Post (my bolds):

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.
(...)
"There is more attack now on the Bush side against Kerry than you've historically had in the general-election period against either candidate," said University of Pennsylvania professor Kathleen Hall Jamieson, an authority on political communication. "This is a very high level of attack, particularly for an incumbent."

Ahh, the sweet smell of desperation....
