Sen. Mitch McConnell and his wife were harassed again at a Louisville restaurant. A man came up to his table and started yelling at him and then threw his take-out box on the ground. It's becoming common for protestors to publicly berate and harass political leaders that they oppose. Such incivility is out of bounds and should be called out. Now home-made bombs addressed to former Pres. Obama, Hillary Clinton and Democratic mega-donor George Soros were intercepted by authorities. They appear to be linked to the same source. Such threats of violence have no place in our republic. It's become incumbent on every citizen to insist upon civil treatment of our leaders. If the incivility continues we can only expect more threats of violence.
