Every time Trump gives a speech attacking Hillary, after he makes his point he should say: "SIGH!"
It should be a running gag at his speeches, and after he does it a few times, he should start egging on his audiences to shout it with a look and a hand gesture when he mentions her name.
The media would DEFINITELY cover that, which would bring Hillary's moment to public attention, plus make her the butt (the BIG butt) of a joke that would stick.
I like the way you think.....
