It was a silly shit-stirring ambush-question, a failed moral equivalency attempt.
1. Melissa Hortman was a state legislator, not a nationwide figure. It's a large difference in scope of influence.
2. The assassin had no coherent political motive/agenda. He was a nutjpb with some sort of messianic complex over obscure concerns or personal conflicts.
IOW, the assassination of Melissa Hortman truly was a "local story", not of national scope.
