Unfortunately, Trig-truther readers are smarter than Fox News viewers, but not by much:

Some news audiences are more politically savvy than others, according to a new poll, with readers of The New Yorker and similar high-brow magazines being the most knowledgeable.
The survey, conducted between April 30 and June 1 by the Pew Research Center for the People & the Press, measured the political knowledge of 3,612 U.S. adults. Participants were asked to name the controlling party of the U.S. House of Representatives, the U.S. secretary of state and Great Britain’s prime minister.
Overall, just 18 percent of participants answered all three questions correctly.
More than 50 percent of Americans knew that the Democrats have a majority in the House, while 42 percent could identify the secretary of state (Condoleezza Rice). Less than 30 percent could name the prime minister of Great Britain (Gordon Brown).
Perfect scores
The best-informed news audiences crossed the ideological spectrum. Nearly half of regular readers of The New Yorker, The Atlantic and Harper’s Magazine answered all three political knowledge questions correctly.
A perfect score was obtained by 44 percent of regular listeners of National Public Radio (NPR), 43 percent of regular viewers of MSNBC’s “Hardball with Chris Matthews” and 42 percent of the Fox News Channel’s “Hannity & Colmes” audience. Thirty-four percent of “The Colbert Report” audience and 30 percent of “The Daily Show” audience got all three questions correct.

The breakdown:

The New Yorker/Atlantic: 71 percent (correctly identified Democrats as the majority in the House), 71 percent (correctly identified Condeleeza Rice), 59 percent (correctly identified Gordon Brown) NPR: 73 percent, 72 percent, 57percent Hannity & Colmes: 84 percent, 73 percent, 49 percent Rush Limbaugh: 83 percent, 71 percent, 41 percent Colbert Report: 73 percent, 65 percent, 49 percent Daily Show: 65 percent, 48 percent, 36 percent NewsHour: 66 percent, 52 percent, 47 percent O’Reilly Factor: 70 percent, 60 percent, 41 percent C-SPAN: 63 percent, 59 percent, 35 percent Letterman/Leno: 51 percent, 42 percent, 31 percent CNN: 59 percent, 48 percent, 29 percent National Enquirer: 44 percent, 32 percent, 22 percent
