hey definitely won't call him Senator Cougar, but the push for John Mellencamp to seek the Democratic nomination to replace the retiring Evan Bayh is gaining steam. According to the AP, an online campaign to encourage the singer to run is running rampant on Facebook and Twitter.

Twitter is a buzz is abuzz with the rumor and three separate Facebook groups have been set up, with the largest boasting about 2,000 members.

Mellencamp is no stranger to politics. In 2008, he recorded a radio commercial supporting Barack Obama's presidential campaign and requested that Republican candidate John McCain stop playing his songs, including "Our Country" and "Pink Houses," at his rallies.
