One of the things we've learned during the Obama era is how important norms are, because we've seen how the Republican Party behaved against Obama. So much of what they did was to smash pre-existing norms, which were nothing more than assumptions of how people would behave, which didn't have any real basis in rules or limits.

Because many people remembered a time when the Republican Party was not so extreme, and hadn't full grasped how much it had changed, people blamed Obama for his failure to get Republicans to agree with him. That blame coloured so much of how the public saw Obama during his presidency. The public thought he was dealing with a brand of Republican leader that just didn't exist any more.

It's absolutely true that people who believed Hillary Clinton would be a decent or even strong nominee need to think why that got that wrong. Laying the entire blame at the feet of Russia and the FBI is not sufficient. The biggest reason things went wrong were her own choices and her own weaknesses.

There's an element of clowning and entertainment to Trump, that makes it surreal and hard to understand to what extent he is pretending to be a fascist or an authoritarian.

Trump was the logical outcome of the Republican's irrational, racialized backlash to Obama that had utterly come to dominate the party's thinking.

The story of the Republican Party is of a far-right that has moved from the fringes of the party to a complete domination of the party. The moderate, mainstream and pragmatic leaders of the party have been pushed out or died off.
