Is the presidential election shaping up as a referendum on which major party candidate is less of a threat to the Constitution? That’s one takeaway from independent candidate Robert F. Kennedy Jr.’s claim that, compared to President Trump, “President Biden is the much worse threat to democracy.” That’s quite a contrast with the view from the left and from even some Republicans who say they see Mr. Trump as a menace to America’s democratic norms.

Mr. Kennedy isn’t glossing over Mr. Trump’s actions around January 6, which Mr. Kenndy frames as an attempt to overturn the 2020 vote. “I’m not going to defend President Trump on that, and it was appalling,” he tells CNN, and “trying to overthrow the election clearly is a threat to democracy.” Mr. Biden poses even more danger to the Constitution, though, “because,” Mr. Kennedy avers, “the First Amendment is the most important.”
