I agree that policy positions don't matter much. But I think strong universal programs matter a lot. It has been so long since we have had any policy implementation that seemed genuinely positive for regular people -- that people could recognize as the government helping them.
They matter a lot *once they are implemented.* I do not think that e.g. calling for Medicare for All would, in itself, have much of an impact on a candidate's election chances. I think that *delivering* Medicare for All would have a very big impact on their reelection chances.
Agree. You said it more clearly.
It's great to debate policy, but this often devolves into overly complex argument and, when it happens, implementation. The academic/pundit class needs to realize that they can often do more by simplifying existing law/government than by heaping on more. Universalism is good.
