(AllHipHop.com) President Barack Obama continues to harness the power of Hip-Hop music before the General Elections, this time utilizing the drawing power of Chicago rapper Common. On Saturday (October 30th), Common will hit the stage in support of President Obama, who will host a massive rally in Hyde Park. Common is expected to perform at the rally at the Midway Plaisance Park, which is close to the University of Chicago's campus. The event, which is free to the public, is one of several events that President Obama has hosted in order to drum up support for Democrats in local elections. Earlier this month, President Obama tapped The Roots and DJ Diamond Kuts to appear on stage during a campaign rally for Democratic hopeful Joe Sestak. Just this week, it was reported that Hip-Hop mega-star Jay-Z would be involved in the Presidents 2012 bid for re-election. President Obama's rally in Chicago featuring Common kicks off at 4:30PM.
