Yes, you are wrong. Most people in the middle need to make a good living to support their family and have a retirement.
And if such a person honestly believes that a second Trump administration will fight harder for those things than Bernie Fucking Sanders, they can be safely ignored on the grounds that they are probably missing the entirety of their brain.
You do realize the moral conservatives voted for Trump. The fiscal conservatives voted for Trump. The hawks voted for Trump. And poor white people have been voting Republican for a couple decades now. And they'll vote for Trump over Sanders. And Independents will have to choose between the communist (he'll be labeled as a Mao Tse Tung wannabe) or the evil they know. Sanders won't win.
Trump in 2016 is not Trump in 2020, and his base has shrunk in the interim, not grown. Therefore, if every single Trump voter from 2016 voted for Trump again, and every single Hillary voter from 2016 votes for Sanders, Sanders still wins because the progressives and former non-voters push him over the edge. There's no escaping this without suggesting Hillary voters changing their minds and voting for Trump, which is an odd hill for your point to die on.
And all of this, even if Sanders does win, he won't be able to advance his platform as Congress passes the bills. And do you honestly think UHC could survive SCOTUS at this time?
You don't get it. He isn't counting on Congress to come quietly, he's counting on a resurgent left wing of mobilized, working-class people to apply pressure from below to extract concessions from their representatives. That's what all of this has been about from day 1, and the most important difference between him and Warren (who apparently thinks Congress will just accept her plans after a polite session of rational debate). It's why he plans on being "organizer-in-chief", using the bully pulpit to remind the majority of people that they have power when they band together. All around the world, as we speak, this is being demonstrated before our eyes in Haiti, Ecuador, Chile, Catalonia, and elsewhere. It was demonstrated in Puerto Rico, in France, and in this country with the massive teachers' strike that is still ongoing.
Bernie is about movement politics, not parliamentarian politics, and his is the only strategy that has ever changed society on a fundamental level anywhere. When that scenario is on the table, it attracts the scorn of conservatives like yourself and Harry. I'm not using that term in the idiosyncratic American sense, but as what it really means: opposed to any disruption of the status quo driven by popular mobilization of the poor and working class. And when such an obvious movement picks up the momentum that it has, throwing rocks from the outside by whining about rich independents, Trump voters, and electability instead of adding your voice
is opposition to that movement, plain and simple.
