Before we melt down about Philadelphia, MS, remember that the Neshoba County fair is the biggest annual political event of the state. If Hillary were going to campaign in Mississippi in July, that's where she would have gone.
Still a disgrace that Trump apparently supports our "flag" though.
That may be true to the residents of Mississippi, but, outside the state, the Neshoba County fair has only one major significance.
Every single Mississippi politican, white or black, Republican or Democrat, no matter how conservative or liberal, campaigns at the Neshoba County Fair. I can't imagine that many people outside the state knowing that the Neshoba County Fair exists without knowing that fact.
Trump Jr. (and lots of other Republican politicians) should certainly be condemned for the things he said there, but no one should ever be condemned for going there, because there is no more natural place in Mississippi to go. The fact that it's in the same county as the civil rights murders is a coincidence.
