Of course it's a ramshackle and gerrymandered system. That's why a minority of Republican voters can control both houses of Congress, though the Republicans get more votes.

But if Trump goes down in flames, and drags the Republican Party down with him, that's his doing, through what he has done and said.

As for Bernie Sanders and the Democrat establishment, equally obviously they will have done everything they could to stop, as their opposite numbers in tge British Labour Party did, and are still doing, to Jeremy Corbyn. But what else could you expect? That's done and dusted, and the only way the movement backing him will get anywhere is with a victory against Trump, and a running battle with Clinton's administration.

Trump winning offers nothing but a kind of national auto-da-fe.
