Reporters (who only want unbiased truth and are totally not in the tank for Hillary) are worried. Something is amiss in Democrat-land. Bernie Sanders is still in the race and - wait for it - he's a man. Hillary, on the other hand, is a woman. So, clearly, there's some sort of "ism" at work here.
No, it's not socialism. They're both socialists. It's one of the other "isms."
