@Are0h Sanders is just a distraction. What really offended most of the people present was that she said that they had profited from Trump, that, in all truth, they had made him president.
Also, the Dems were offended because she said they're so clueless that they would even lose to someone named Jim Paedophile Nazi Doctor. And that's true, too.
That's why they use the comment about Sanders to attack Wolf, because they don't want to draw attention to everything else she said.
