The most ridiculous sound in the world has gotta' be the one of an overbearing Barack Obama rattling his saber at Brits who want out of the EU.
It's going to take more than insipid "back off" orders from from the likes of Obama to frighten Brits from voting the way they want on Brexit.
A feeble quack from a lame duck on his way out of public office will never dim the knowledge that it comes from a no-boots-on-the-ground in jihadist-held territory, no-skin-in-any-game-but-his-own, semi-golf pro, part-time president.
