WASHINGTON (CNN) - John McCain's campaign will stop advertising on several pro-Hillary Clinton Web sites that have attacked Barack Obama for being unpatriotic and, in one case, compared the Democratic nominee-in-waiting to Adolf Hitler.
A spokesman for McCain said Monday the campaign was not aware their ads were running on the offending Web sites, and has taken steps to block those sites from their online advertising network.
"When we find stuff like this, we take care of it," said McCain spokesman Brian Rogers.
McCain has made it known he is reaching out to former Clinton supporters, and there are nearly two hundred well-trafficked blogs and online communities run by former Clinton supporters who refuse to support Obama. But the three sites on which McCain's ads appeared are particularly hostile to the Illinois senator.
One Web site, called Stop-Obama.org, is a group blog comprised of disaffected Clinton supporters, some of whom are now supporting McCain. Three different banners ads, one of which featured McCain standing side-by-side with Sen. Joseph Lieberman, were running on the site until Monday.
A recent post on the blog outlined the "simple parallels" between Obama and Hitler, and accused Obama's audiences of having the same cult mentality that characterized followers of the German dictator.
