Brendan Nyhan pops up on Time.com's new political website to discuss the recent severing of his relationship with lefty mag The American Prospect. Nyhan resigned on Friday, after top brass decided he was being too evenhanded. Nyhan's essay brings up some interesting points about how the rise of political blogs is affecting the fiscal health of partisan print magazines like TAP, but we've got a feeling that there was something else in the story that resonated with Time.com Washington editor Ana Marie Cox. After all, the tale of a Prospect employee parting ways with the magazine for failing to toe the liberal line has to resonate with her on some level. Memo to TAPpers: If you can't sing "Joe Hill" in unison, you might be better off singing somewhere else.
