Good ole’ Nigel. The world owes him quite a lot. He helped craft Brexit which was a revolt against the global crony system. Brexit was a very public rebuke of the EU, bureaucracy generally, the cronycrats in Brussels specifically, George Soros, and organizations like the Clinton Foundation. As such Mr. Farage is hated by the cocktail party crowd. Nigel called the crony class out and then he whipped them in front of the world.
So the cronies are a bit sore about the whole thing.
