I'm actually sad to see Sanders do this. Trump is just scraping the bottom of the barrel for attention at this point, and Sanders has nothing to gain from addressing any of Trump's sad talking points. No one in the Democrat base is interested in voting for Trump anyway... Makes me feel like Sanders is just trying to get some media attention of his own by being the voice of reason that shuts down Trump.

Then again, Sanders has done nothing but talk of the issues so far, and it's just getting him so far in the battle for public attention. It feels desperate to engage Trump... It's not like Clinton's doing it, and she was the one targeted by Trump's stupid comment.
