I really wish people would stop with the affectionate, avuncular "Bernie." He's a US Senator and the diminutive first name thing diminishes him.
When I saw "the left" in your title I assumed you were a Trump supporter or at least a Republican; anyone with any grasp of the global political continuum knows that there is no "left" in the USA, unless you count a few college freshmen wearing berets and smoking Galoises. Nobody in politics is far enough left to repudiate capitalism or proudly wear the mantle of "Socialist." Today's Democrats are probably to the right of Reagan. We have a relatively-left, not an honest-to-god left.
