During the 2008 presidential election, MSNBC's coverage was anchored by Olbermann, Chris Matthews, and David Gregory. They were widely viewed as the face of the channel's political coverage. During the first three months of the presidential campaign, MSNBC's ratings grew by 158 percent. Olbermann and Matthews, however, were criticized for expressing left-leaning opinions on the channel. Both were later removed from their anchor positions. Audience viewership during the 2008 presidential campaign more than doubled from the 2004 presidential election, and the channel topped CNN in ratings for the first time during the last three months of the campaign in the key 25–54 age demographic.
