Cable news chatter is changing the electoral landscape

From The Washington Post:

On any given night, a parade of Democratic lawmakers and candidates appears on MSNBC, while Republicans flock to Fox - including some, such as O'Donnell, Rep. Michele Bachmann (Minn.) and Sharron Angle, who grant few interviews elsewhere. CNN has a more balanced guest lineup and no openly partisan shows, but its prime-time ratings have declined substantially.
