So Donald Trump Jr went to the Neshoba County Fair in Mississippi this week, where he said, vis-a-vis the Mississippi state flag, which is the only state flag that still invokes the Confederacy, “I believe in tradition.” Those Neshoba County fairgrounds are just a few miles from Philadelphia, Mississippi. The place indelibly associated with the murder of James Chaney, Andrew Goodman, and Michael Schwerner in 1964. So that tells you a lot about Donald Trump. Junior and Senior.

But it also tells you a lot about the Republican Party. Thirty-six years ago, almost to the day, Ronald Reagan, then a candidate for the presidency, also went to the Neshoba County Fair in Mississippi. There, he said, “I believe in states’ rights.” That, of course, had been the slogan for decades of racial segregation and Jim Crow. Like father, like son; like Reagan, like Trump.

But it also tells you something about the Democratic Party.
