I was at the 1968 police riot. My father went down there looking for my brother and I, since he had told us not to go. He got swept up in the events while searching for us. As a veteran of D-day and the Battle of the Bulge he was shocked to see American troops pointing weapons at peaceful demonstrators. He told me later we did not live in a democracy and he never voted again.
The Democratic party has run it’s rope out. Unless they completely give up their attempts to hold their neo-liberal stance and turn the party over to the Sanders and Warren wing they are done. It is true that our political system is rigged to a winner take all two party system. However if the DNC elite do not surrender (which they will not) enough people will simply sit it out or vote for a 3rd party which more honestly represents their views. And the Democratic party will never win a national election again and will continue to loose more congressional seats.
It is time for a left, economically populist party or else it will all go to the neo-facist right.
