Trump is an oaf. Unfortunatly his opponent is a narcissist, liar, statist, criminal, thug, dipshit, uh, .... and so forth.
The idea that he was threatening violence must be inferred from his statement. The idea he was threatening Ms. Clinton requires a larger inference. But, unfortunatly neither inference is completly unreasonable. Thus my suggestion that Trump is an oaf.
But I prefer oafs to ..... *SIGH!* ..... Hillary.
