The conservative talk giant claims that cable TV network MSNBC is trying to “build its ratings on my back,” and wants the liberal-leaning channel to go a month without mentioning him by name. Limbaugh said on his radio show, “I challenge you, MSNBC! Thirty days without anything mentioning me. No video of me, no guests commenting on me.” Limbaugh said on his show, “they (MSNBC) cannot…go any appreciable length of time without showing video of me, the CPAC speech or excerpts from this radio show or having a bunch of hack guests on to discuss me.” You can read Rush’s transcript of his MSNBC comments by clicking here. MSNBC is known for discussing Limbaugh’s stance on President Obama, and showing video of Limbaugh, including footage of the talker bouncing on the stage during his keynote speech to the Conservative Political Action Conference.
