Contrarian: Descriptive Not Prescriptive

I'll probably be alone in this, but my interpretation of Trump's statement is, it's a one-sentence digression describing what the gun nuts could do if his prediction of Clinton taking away guns came true.  I'm led to this because Trump famously isn't big on Second Amendment rights, or hasn't been in his past. So he outlines a sequence: Hillary aiming to take guns away (wrong), appointing Justices who share her aim (wrong because she doesn't aim to take guns away), yielding an inevitable result if you don't elect Trump.  But Trump's mind, which skitters like a moose calf on ice, undermines his projection by playing with the idea that gun nuts might assassinate Clinton.  It's not pushing the idea, it's the spur of the moment statement of a smart ass who never leaves a thought, or nonthought, unexpressed.
