In some ways, Trump is just going to continue the trend: by continuing the norm-smashing behaviour that Republicans used in opposition.

Donald Trump will be a tragedy, a sad joke in American history.

At best, Trumpism will be a more right-wing version of the same old Republican Party.

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.

American democracy faces a massive challenge. I don't think it is a certainty that we're headed toward Putin's Russia, as some commentariat does. But people need to mobilize and build up small-d democratic institutions to prepare against that eventuality.

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.

It's possible that Trump will have success by staging jobs theatre, rather than creating jobs. It's the inverse of what Obama did: saving an enormous amount of jobs without having the televised theatre to go along with it.
