Trumpism isn’t an ideology — it's a fighting posture

Donald Trump is no longer President of the United States, but even without a Twitter account from which to lob rhetorical bombs at his adversaries, Trump has held sway over the Republican Party via proxy battles among congressional Republicans and rumblings about his potential next moves.

There are several theories about what Trump’s appeal to Republicans was all about and why it might stick around. Is it a cult of personality about Trump alone? Is it a policy agenda that reorients the party in a more populist or big-government direction?
