The only thing I can think of is that we would have Pence to take his place.
But that could be easily resolved.
I think that his administration is SO INCOMPETENT that it would be a piece of cake to off this moron. He is a moron surrounded by morons. But no one, not even those 911 responders he invited in to the Oval who had nothing to lose because they are already too far gone, did not bring a shiv in to do him in.
Are we so dead in this country that even the killers have given up hope? We have moron psychos killing innocent children in schools and no one hates Trump enough? We have killers who hate kids but not Trump? We have killers who want to make a name for themselves.
And poetic justice would be for the NEXT president to pardon the killer. That would be rad and progressive in a great way.
