If you discount for the self-serving absurdities and occasional misstatement, the first part of RFK Jr.’s speech on Friday was a pretty powerful indictment of the Democratic complex and possibly the most cogent case against how we arrived at nominee Kamala Harris that we’ve heard from a national politician. By the time he got to Ukraine, he completely lost me. Still, even if you disagreed with all of it, it was a speech that tried to build its arguments brick by brick and, at that level, was an admirable act of attempted persuasion.
