Obama launches anti-robocall site

Hitting back at automated phone calls and other attacks from John McCain, Barack Obama's campaign today launched a website where supporters can report new assaults -- and get the campaign's defense.

"John McCain has launched a new round of false, vicious robocalls, mailers, and attack ads – despite being warned to change his tone by a string of Republican leaders including Colin Powell and four sitting Republican senators. To combat his renewed effort to smear Barack Obama, the Obama campaign today launched a fact-checking campaign centered around a new website," the Obama campaign said.

The website "allows voters to report new attacks that pop up in their area – and get the facts about smears they’ve heard," it said.

The site is in addition to one it launched in June to rebut the flurry of what it called "smears" bouncing around the Internet.
