@edgarblythe,
The only link I see is a strategy, not the characters of either Trump or Sanders. Nor the characters of either supporters. To borrow Hillary's term and possibly get some flak, for the most part Trump's core base who actually think and believe in his rhetoric, both implied and told outright, they are mostly the deplorables who used to be on the fringes who managed to slide by into mainstream. Bernie supporters believe in the things Bernie is for and they are all good things.
However, Bernie does whip up victimization to the ninth degree and goes on about the corrupt of the DNC to divide and conquer democrats so that he has a better chance of winning. He was kind of being overshadowed by all the progressives, so he is back on track now. We'll see if his idea of employers giving saving of Medicare for All for wages and benefits to their employees will help put him back over Warren and perhaps top Biden.
