I think what he is getting at is that democrats could be more “aggressive” in how to appeals to the working class people. These subtle policies that have marginal benefit don’t have enough perceived impact.
Democrats could promise something simple and with clear benefits to common folks, something that can be easily understood. People want change. I think Bernie was almost getting there when he was running.
MAGA fans have jumped on the bandwagon of “sticking it to the man”, and “draining the swamp”. Which is kind of what Bernie wants to do but sincerely, with a track record to prove it.
Edit: added “perceived “
Or a tax?
