Donald Trump has a knack for nicknames. Low-energy Jeb caught something of Jeb's entitled aura. "Little Marco" got at something truly juvenile and naive about Marco Rubio. And "Lyin' Ted" was an effective way of branding Ted Cruz's dishonesty. Lately, Donald's been trying new nicknames for Hillary Clinton, but he seems to like his original "Crooked Hillary" best.
And his first instinct is best. The Clinton Foundation and other associated concerns really are a kind of globalist grift.
