To regard this think tank as a "propaganda organization", you would need to find a reliable source stating that it is a propaganda organization. All anyone's been able to do is find the appropriate verb. Which, would be found by reliable sources reporting on the Clinton campaign, the Obama campaign, the Bachmann campaign, and any number of political interest groups or political parties. Type in "propagandizing" and list a newspaper, political party, think-tank, or even university, and you'll see what I mean. Like this on the Obama campaign  To make inferences from that opinion piece published in a reliable source, and therefore label his campaign a "propaganda organization", or himself a "master propagandist", would of course be very subjective.
