Libertarian Gary Johnson to run for White House

The Libertarian Party has nominated Gary Johnson as its presidential candidate, believing he can challenge presumptive Republican nominee Donald Trump and Democratic frontrunner Hillary Clinton because of their poor showing in popularity polls.

Mr Johnson, 63, won the nomination on the second ballot at the party’s convention in Orlando, Florida, defeating Austin Petersen, founder of The Libertarian Republic magazine, and anti-computer virus company founder John McAfee.

The delegates selected former Massachusetts governor William Weld to be his vice-presidential running mate.
