A president hobbled domestically by his own party’s divisions and the opposition’s new energy may be tempted — Putin-like — to change the subject in a way that vaults him back to popularity. A foreign altercation from which he will not back down? A trade war? A smidge likelier, I’d say, is an over-the-top response to an inevitable jihadist terror attack in a major American city. A demagogue loses much of his power when he tries to wrestle complicated legislation through various political factions, in the way our gloriously inefficient Constitution requires. He regains it with rank fear, polarization, and a raw show of force. Heaven knows what the Constitution will look like once he’s finished.
