Wealth message aside, there will always be a few Dems who will undermine the general message of the party. Willing to do it to get the attention with enough distractions that feed the opposition with what they want. That is to get the middle to lean right. BTW, was that the event that had a costly ticket to attend?
The MSM helps willingly because the objective is eyeballs. They care as much about social conditions as the ratings will generate.
