Do Democrats have a 'messaging problem'?

I just wrapped up a live appearance on CNN News Central with anchor John Berman and Democrat Bakari Sellers. There was one topic we didn’t get to that I really wanted to discuss, so here’s a quick video dispatch from the home office on U.S. Senator Mark Kelly (D-AZ) claiming that Democrats merely have a “messaging problem.” And to fix that? They’re starting to post videos of themselves lifting weights and talking policy. Oy.
