For all the recent talk of eliminating the filibuster if Democrats take the Senate, on television news over the last few months it has been Fox News that has been mentioning the topic the most. Interestingly, looking back over the past decade, mentions this year pale in comparison to 2009-2010 and 2012-2014, when it was MSNBC that mentioned it the most. CNN has not spent much time on the topic over the past decade.
