A political blog is a blog that focuses on political matters, including local, state, federal, and international politics. Some political blogs express the point of view of one person, while others are authored by multiple people. Political blogs gained legitimacy in the 2004 U.S. presidential election as bloggers were quick to hold the mainstream media's feet to the fire when reporting election news. In particular, bloggers broke the CBS forged memo story that resulted in several CBS executives being fired and Dan Rather's resignation.
