Ann Coulter is rooting for a Trump-DeSantis throwdown. She's not alone.

When Ms. Coulter turns, she does not go gently. Her critiques of Mr. Trump have included calling him “a shallow, lazy ignoramus,” “a complete moron,” “a blithering idiot” and “a lout.” She now considers his entire presidency a flop. “Trump accomplished everything he was ever going to accomplish at 2 a.m.” on election night in 2016, she emailed me last week. “The best thing that could have happened to the Republican Party (and the country) would have been for him to be vaporized at the moment he was announcing his victory. Pence would have been afraid to betray Trump’s supporters. Trump wasn’t!”…

In her email, Ms. Coulter got even more personal. “DeSantis is better than Trump, for many, many reasons, including: He won’t bring Jared and Ivanka into the White House.” She also expressed confidence that Mr. DeSantis can handle Mr. Trump. “He’s mostly just ignoring the 11-year-old. Unlike Trump, DeSantis has a day job.”

Having split with Mr. Trump, Ms. Coulter has an obvious interest in pushing the line that he is a washed-up relic. That said, the gal has a track record for sensing — and exploiting — political vulnerabilities.
