With 35 right-leaning guests and 16 from the left (69 percent vs. 31 percent), the right had a better than 2 to 1 advantage.
Right-wing syndicated talk show host Laura Ingraham appeared seven times, more frequently than any other guest; the second-most prominent guest (6 appearances) was conservative National Review editor Rich Lowry. (The third most frequent guest was Time’s Karen Tumulty, with five appearances.)
Reliable Sources' conservative guests not only appeared more often than their progressive counterparts, they tended to be more staunchly ideological; many are avowed activists and campaigners for the conservative movement, like talkshow host Rush Limbaugh or Jay Nordlinger and Byron York of the National Review.
New York Times columnist Frank Rich and internet blogger Joshua Micah Marshall of www.talkingpointsmemo.com
were the most frequent left-of-center guests with three spots each. No other left-leaning guest appeared more than once in the year studied. Reliable Sources drew no guests from National Review's progressive counterparts--magazines like In These Times, The Progressive or The Nation.
