What Mr. Trump borrows from Jackson is not an issue, but a way of thinking about the world. Mr. Trump promises to fix his supporters’ problems, no matter who else is hurt. He’s a wealthy celebrity always ready for a fight, a superpatriot who says he will make America great again. He vows to attack government corruption and defend the common man. All this could be said of Jackson…

Jackson had a captivating style, and not just because of his wild hair. He did what he wanted, and demanded respect. In an 1806 duel, he shot and killed a man who had insulted him in a newspaper. Mr. Trump’s Twitter broadsides at his critics are gentle by comparison.

Like Mr. Trump, Jackson made his fortune in real estate. He bought and sold vast tracts of Southern land in concert with wealthy friends. If desirable land was owned by Indians, Jackson bullied or bribed them into selling it cheap.

And again like Mr. Trump, a former Democrat and independent, Jackson did not worry about consistency. Having joined the nation’s wealthy elite, he ran for president as an opponent of wealthy elites. He defended liberty while operating a personal empire of cotton plantations using hundreds of enslaved black laborers.
