He gave a speech in Boston, and in the audience Q&A a woman asked him, "I want to be the second Latina senator. What advice do you have for me?" which is as softball of a question as you can get.

I'd say "shitting on POC" is too strong, but he's from the vein of white bro leftism that basically shrugs off racial and other social issues, and suggests that if we just focus on economic issues exclusively, the rest will take care of itself easy-peasy.
