Sixty-six percent of Americans have never heard of Gary Johnson. Almost six percent are voting for him. If turnout roughly mirrors 2012 levels, of the estimated 126 million likely voters, around 7.5  million will vote for Johnson. This would be the most support a Libertarian party candidate has received in history, and in fact, more than the sum of all the votes the Libertarian Party has received in every presidential election to date.

Donald Trump and Hillary Clinton are the number one and number two most disliked presidential nominees of all time according to the renowned political analysis website FiveThirtyEight, and so some voters have turned to Gary Johnson simply to avoid having to choose one of the two major candidates. However, voters should realize that given the seriousness of this election and the disastrous consequences of a Trump presidency, a vote for Johnson is a vote for Trump. Even low levels of support for a third party candidate can prove decisive, as evidenced by George Bush’s victory in 2000. In that election, Ralph Nader garnered the support of just 2% of Americans, but still cost Al Gore the election in Florida.

An even  more significant problem with casting a protest vote for Johnson is that by pausing to consider his policies, one quickly finds that he is far from an ideal candidate. In an interview with Scott Holleran in 2011, Johnson said that he would end the Department of Education and the Department of Housing and Urban Development. The Libertarian Party, in its platform, would phase out the Social Security program, saying that “members of society will become even more charitable and civil society will be strengthened as government reduces its activity in [retirement planning].” On abortion, its official stance is that it is a “sensitive issue,” and that the government “should be kept out of the matter.”

Speaking to the National Press Club about global warming in 2011, Johnson advocated ignoring the pressing issue of climate change. He asserts that “in billions of years, the sun is going to actually grow and encompass the Earth, right? So global warming is in our future.” And finally, arguably the most memorable moment of his 2016 campaign, in an interview with MSNBC in which he was asked about the ongoing conflict in Syria, Johnson responded, “what is Aleppo?”

Gary Johnson is not the right candidate for President of the United States. He is no replacement for Bernie Sanders, despite what some may believe—the only issue they agree on  is legalizing marijuana—and he’s not at all progressive. Johnson’s beliefs are as ignorant as they are extreme. Most of his supporters most likely hold political views closer to those of Hillary Clinton but, for whatever reason, refuse to vote for her.

All 18 million Johnson voters, Democrat or Libertarian, can agree that of the three candidates, a Trump presidency would be the worst outcome. But a vote for Johnson is a vote for Trump, and by stealing some votes that could have otherwise gone to Clinton, Johnson will make the race just a little tighter.
