The minisite, simply named Hillary Attacks, catalogs negative newspaper articles, speeches and press releases that the New York senator's campaign has issued that the Obama campaign says are personal attacks on Obama's character.

"Today we're launching a website that will keep track of all the attacks Senator Clinton has launched since she said she wasn't interested in attacking other Democrats at the Jefferson-Jackson Dinner on November 10," campaign manager David Plouffe wrote

This is a "very, very impressive effort to enlist the full range of online campaign tools to exploit Hillary's biggest mistake in the campaign to date, which was to go after Obama's personal history (as opposed to his record and rhetoric) and say it was fun," notes Michael Cornfield, vice president of research and media strategy at consulting firm 720 Strategies in Washington D.C.

Negative campaigning has traditionally turned voters off

polling shows that Iowans believe Clinton runs the most negative campaign.
