PRO: Host of MSNBC's Countdown with Keith Olbermann, which has adopted an opinion-oriented format critical of Republicans and conservatives in direct competition with Fox's The O'Reilly Factor.
CON: Despite increasing viewership 82% over the past year to an average of 706,000 total viewers, Countdown remains a distant second to O'Reilly, who averages 2.45 million viewers.
