Chicago Tribune endorses Libertarian Gary Johnson for president
The board wrote they believed "this is the moment to rebuke the Republican and Democratic parties."
"We reject the cliche that a citizen who chooses a principled third-party candidate is squandering his or her vote," they wrote.
Speaking with WGN, Editorial Board Editor John McCormick said they just couldn't endorse either the candidate from the major parties.
"We wound up with all those Americans who say, 'I'm fed up this year, I'm really tired of the parties, I really dislike the choices, if only I could cast a vote I could be proud of, if only I could vote for a candidate I admire,'" McCormick said.
McCormick said the board decided back in March that Republican nominee Donald Trump is "not capable" of being president.
"He has gone out of his way to anger a lot of world leaders, he angers an awful lot of the American public, and he doesn't have the character or disposition for the job," he said.
In the case of Democrat Hillary Clinton, McCormick said that while they believe she's capable of being president, she's "not the best candidate for the job."
"An awful lot of Americans just don't trust her... she seems to have a problem with straight talk," McCormick said.
Additionally, McCormick said they disagree with both candidates' stances on international trade in particular, such as their opposition to the Trans-Pacific Partnership.
"If you live in the Midwest, if you live in Chicago, and you're not in favor of more and more and more international trade, what's your problem? This is a huge part of our economy here," McCormick said.
