On Wednesday's broadcast of CNN's "The Source," Biden Campaign Co-Chair Sen. Chris Coons (D-DE) said that he has told his Senate colleagues, "remember who Joe Biden is. We can't set a bar so high that who Joe Biden's been for 30 years can't clear it. He's always had a slight stutter. He's always spoken a little off the cuff." And that we shouldn't "set the stakes too high" for his NATO press conference on Thursday.
