The Jessica Sanchez bus keeps on rolling. The American Idol alum was invited to perform at last week’s 2012 Democratic National Convention. She sang a cover of “You’re All I Need to Get By” by Marvin Gaye and Tammi Terrell in front of a packed house at the political event, and she killed it on stage. As a bonus, you get to see a more awkward middle aged dancing than a wedding reception in the middle of Utah.
