If the voters of this country (aided by Republican vote-suppression and Russian interference) vote for Trump--a veritable "Teflon don," with a crime history going back decades--over any of the Democratic candidates, they deserve what they get.
Democratic proposals have wide appeal (according to polls), and they shouldn't have to be repudiated or watered down to appeal to Republicans. If we can't get enough people out to vote to overcome all the roadblocks thrown in our way, it will be on us. I believe, considering the success of progressives in the 2018 congressional races, that an overwhelming win is entirely possible.
