2016 Postmortem
In reply to the discussion: Stop 3/5ing the vote of the AA community. [View all]Warren DeMontague
(80,708 posts)people who support sanders, and your response in essence was "fuck em since they're all white guys".
I've suggested for a while that Hillary ought to look at the Demographics - outside the echo chamber of people who honestly believe the ONLY person supporting Sanders has been a fedora-wearing redditor with a soul patch and a purple shirt - where she isn't doing as well; think Millennials- and ask how to better inspire and motivate and win them over.
Sanders, obviously, has a problem with minority voters, or has so far like he did today. I don't dispute that, I can speculate as to potential reasons as to why that might be, but unlike the people you mention your OP (which clearly is referencing Sanders supporters, even if you didn't say it in so many words) I'm not going to denigrate the opinions of those voters or tell them who they "should" support. They've made their preference clear and more power to em.
But Sanders having a problem w/those demographics doesnt matter if he's not the nominee. Hillary will need to win in November.
