Unpopular among many Americans, Hillary Clinton and Donald Trump have opened the door for a third-party spoiler in the presidential campaign — and just as Gary Johnson is starting to warm up. The folksy Libertarian, a former Republican governor of New Mexico, is on the ballot in 50 states. Green Party nominee Jill Stein is on the ballot in about half. Neither is remotely within reach of carrying a state. Nor do Johnson or Stein appear to be in a position to tip any states toward Trump. But there’s a chance that Johnson could move a close race toward Clinton, in much the same way that Ralph Nader pulled enough votes away from Al Gore in 2000 to hand Florida to George W. Bush.
