I think its a clever turn of phrase. We should put it on teeshirts and wear it. “Basket of Deplorables, Coming to Make America Great Again...”
It’s not at all clever. What does basket have to do with people? Baskets are not used for people unless we’re talking about babies being left on doorways in the 18th century! And I doubt the brilliant Hillary was referring to that.
And that’s the point: Hillary has no talent for wordplay or anything else. Trump has. He would never have used this clunky phrase. He’s a wit.
Harridan Hillary is a moral basket case.
