Bernie Sanders or Beto O'Rourke

This is a decision that progressives must face in the near future: Will it be the Bern or newbie Beto? In health care O'Rourke supports the Medicare for America plan, Sanders the Single-payer Medicare-for-all America. Just recently there were articles exclaiming that Bernie Sanders would not be able to get rid of insurance companies, a part of the latter plan. The two are very similar on other Progressive issues and while we know exactly what Bernie stands for, Beto will have to better qualify some of his policies. 2020 will be a race for the ages, at least for Democrats. They know they must beat Trump, but what left candidate is best qualified to do it?
