Up there with his threats to cultural sites and assertions that his critics are traitors, one of President Trump’s more tedious delusions is that he’s a better president than George Washington and Abraham Lincoln. This isn’t just silly — it’s ludicrous, even if you have a high opinion of Trump.

Still, at a rally last week, Trump pointed to a recent YouGov poll that showed 53% to 47% of Republicans view him to be a better president than Lincoln. Trump said he told Melania Trump, “I just beat Abraham Lincoln in a poll.” The president then doubled down on this narrative as he signed a U.S.-China trade deal on Wednesday. Fox Business’s Lou Dobbs says Trump claims that “[Trump is] the greatest [president] of them all. I said, does that include Washington and Lincoln? And he said yes. Now I don’t know if he was for real, but that’s okay.”
