Donald Trump’s campaign reset was barely 24 hours old when he ventured off script and into the familiar territory of controversy, squandering his chances of changing the political conversation yet again.

The GOP presidential nominee passed up opportunities to capitalize on potentially damaging news for Hillary Clinton. Instead of focusing on the fact that the Orlando nightclub shooter’s father attended her rally in Kissimmee, Fla., or that she campaigned for ousted Democratic National Committee Chairwoman Debbie Wasserman Schultz, Trump ignited a new firestorm with a comment that seemed to suggest violence or rebellion by gun rights activists against his political opponent.

“If she gets to pick her judges, nothing you can do, folks,” Trump said at a rally in Wilmington, N.C. “Though the Second Amendment people, maybe there is, I don’t know.”

The remarks fit neatly into Clinton campaign messaging that the GOP nominee lacks the temperament to serve, and Democrats pounced.
