American Thinker (AT) is a conservative daily internet publication. According to it website, American Thinker presents a "thoughtful exploration of issues of importance to Americans." 
There is ample evidence to support the notion that AT serves as part of the right wing's echo chamber.
A good example of this can be found in a December 5th, 2007 piece on the National Intelligence Estimate report on the state of Iran's Nuclear weapon's program.
Writer Ed Lasky first refers to an Editorial in the New York Sun inferring that the intelligence community is against President Bush. Lasky concludes that "the National Intelligence Estimate was cooked up by bureaucrats eager to embarrass George Bush and transform US policy towards Iran." To substantiate his argument he goes on to quote an editorial from the Wall Street Journal which avers the authors of the NIE study are: "former State Department officials with previous reputations that should lead one to doubt their conclusions. All three are ex-bureaucrats who, as is generally true of State Department types, favor endless rounds of negotiation and "diplomacy" and oppose confrontation. These three officials, according to the Wall Street Journal, have 'reputations as hyper-partisan anti-Bush officials'." This statement "Hyper-partisan anti-Bush officials", restated as fact in the AT article, is quoted and requoted by rightwing blogs and news sources throughout the media.
Ultimately this type of statement winds up being echoed by mainstream pundits such as Rush Limbaugh.
