A loud brash supporter of Donald Trump ,seen on the news after some awful incident, against wearing a Red Make America Great Again ball cap or with a vehicle covered in proTrump /right wing /Anti Clinton stickers.
That guy who mailed all those pipe bombs th Obama , Hillary and George Soros what a Magafuck, not as horrid as those Magafucking Nazis at Charlottesville but awful indeed.
