In The Guardian, Marilynne Robinson explores how the Republican Party managed to shoot itself in the foot with Trump. A nugget:
In fact, the Republican situation is such a tangle of unintended consequences that it is impossible to sort it all out, or to make the attempt without laughing. They re-jiggered their primary system to enhance party influence in choosing a candidate, and Trump, the great orange-haired Unintended Consequence, has played their innovations like a fiddle.
For years they have gerrymandered districts to make them “safe” for their representatives in Congress, thereby incubating a culture of politicians who are too odd and extreme – and white – to appeal to a national electorate. Their restrictions on voting can be expected to have the same effect.
In other words, they have seized one kind of power at the cost of another, and in the process exacerbated every demographic problem that threatens their future as a national party.
