If you live in an early primary or caucus state, you’ve probably already had your fill of political advertising. According to The Washington Post, politicians and political groups spent more than $23 million on campaign television ads as of December 1, 2011. With record ad spending predicted for the 2012 election, the rest of the nation will soon be bombarded with television ads “approved by” politicians from the left, right and the center of the political spectrum.

Candidates and those groups that support them need to know where to allocate their ad dollars to either connect with their base or reach swing voters. Experian Simmons analyzed the viewing audiences of over 600 broadcast, cable and syndicated TV programs that were measured in our most recent National Consumer Study in order to pinpoint opportunities for politicians to reach partisans and middle of the road voters. This analysis has already gathered the attention of major media outlets, including Entertainment Weekly, The Washington Post, AOL, Huffington Post and more.

Below are the entertainment and news programs that score the highest concentration of liberal Democrats among their viewers, Conservative Republicans and Middle-of-the-Road Voters registered with any party.
