A top House Democrat has blasted conservative Internet bloggers for spreading lies and “manufactured controversies” about President Obama, equating their actions to Nazi propagandists.

Rep. James Clyburn, D-S.C., told Sirius XM’s POTUS show on Thursday that while race relations have improved in the U.S. under Obama, “right wing bloggers” — with the complicit help of the mainstream media — have unfairly demonized the Obama administration and other favorite conservative targets.

“You have people’s words and phrases being misrepresented and looped through the news media and thrown out there on the Internet, and people run with it because these things start getting reported in the mainstream media, and before you know it, people believe that stuff,” according to an audio link of the assistant House Democratic leader’s satellite radio interview posted on Mediaite.com.

“Now you know, the people of Germany believed Hitler’s foolishness that led to the Holocaust. They believed that stuff. And people will tend to believe what they hear through the media.”

Clyburn said such “manufactured controversies” have had a chilling effect, saying they have led to Congress defunding the community organizing group ACORN, and the firing of former USDA official Shirley Sherrod after an edited video of her surfaced where she made seemingly racist remarks.

“President Obama has had so many of his activities misrepresented, and the [mainstream] media have not been discerning enough, in my opinion, to say to people, ‘this ain’t news, this is foolishness.’”
