Andrea Mitchell invited on DNC Chairman Tim Kaine, on Tuesday’s Andrea Mitchell Reports, to announce the Democrats have picked Charlotte, North Carolina to host their 2012 convention but the MSNBC host couldn’t resist hitting Kaine from the left as she scolded Democrats for selecting a right-to-work state. Mitchell, taking up for Big Labor, even challenged Kaine: “I defy you to find a labor hotel for these delegates, for all the AFL-CIO folks coming to Charlotte.”
