Looking at the headlines in recent months, you'd be forgiven for thinking that only Hillary Clinton and Donald Trump were running for president. Actually, there are a whole lot of presidential hopefuls that might not be on your radar.
You'd be surprised at just how many people are in the running to be the next Commander-in-Chief - the number is in the hundreds. Don't believe us? Check out the full list here.
But we want to know a bit more about the top three candidates that aren't Clinton or Trump.
No third party candidate has received more than 1% of the vote since 2000 when Ralph Nader achieved nearly 3% for the Green Party, but this has been an unpredictable year in politics so who knows what will happen.
So let's take a look at the three third party candidates that are on over 20 state ballots, coming from the Constitution Party of the US and the Green and Libertarian parties.
Gary Johnson: Libertarian Party
Johnson is the former two-term Republican governor of New Mexico, and is currently coming in third in the polls.
This year isn't the first time he's run for president: In 2012 he received 0.99% of the popular vote.
As a Libertarian he holds many classic liberal views such as a belief in the limited role of government and military, and being fiscally conservative.
In 2011 he came under fire for saying that spending money on climate change isn't worthwhile, because "the sun is going to actually grow and encompass the earth, right?" He has since said that the comment was a joke, but added that we should look at colonising a little further afield.
"We do have to inhabit other planets. The future of the human race is space exploration," he told ABC news.
He was caught out on MSNBC for not knowing what or where the Syrian city Aleppo is. He later released a statement saying he was "thinking about an acronym, not the Syrian conflict. I blanked. It happens, and it will happen again during the course of this campaign."
Johnson also said in a HuffPostLive interview that minimum wage isn't an issue.
"Minimum wage is much to do about nothing. Nobody works for minimum wage," he said. In fact, the US Bureau of National Statistics found that in 2014 about 1.7 million people were paid below the federal minimum wage.
Then there was this slightly odd moment in an interview.
Jill Stein: Green Party
Stein isn't a career politician - she trained as a physician and first ran for governor of Massachusetts in 2002. The only elections she's been successful in are in 2005 and 2008 when she was elected as Lexington meeting representative.
Like Johnson, this isn't her first crack at the presidency. She ran as the Green Party's candidate in 2012, receiving 0.36% of the votes.
As we're sure is pretty obvious, the environment is central to Stein's campaign. Her ambitious plan if elected is to transition to all renewable energy sources by 2030.
Another aspect of her policies is vastly reducing military spending and shutting down many bases. She also wants to overhaul the two-party system that dominates American politics.
Her views are similar to those of Bernie Sanders but much more extreme - when he conceded the Democrat nomination to Clinton, Stein wrote an open letter inviting Sanders to defect to the Green Party. Things that she's big on, like Sanders, include the right to healthcare and $15 minimum wage.
There have been suggestions that Stein is against vaccinations. In July she told the Washington Post that she's not sure all "real questions" on vaccines have been addressed.
She also seems to be a bit worried by WiFi. In a Reddit AMA Bromaster 3000 asked: "You once said that 'wi-fi' is a threat to the health of American children? Why do you hold that belief, if you still hold it?"
Stein's somewhat ambiguous response was: "A number of scientific studies have raised red flags about possible health effects of WiFi radiation on young children. I do not have a personal opinion that WiFi is or isn't a health issue for children. There is not enough information to know."
Darrell Castle: Constitution Party of the US
Castle is from Tennessee and served in the Marines during the Vietnam War before working as a lawyer.
Castle is the only one of these three that hasn't run for president before: Instead, he was his party's nominee for vice president in 2008.
As you can tell by the name of his party, central to Castle's beliefs is protecting the constitution. He holds many staunchly conservative Christian beliefs, opposing same-sex marriage and abortion.
Castle is at great odds with Stein: he opposes raising the minimum wage, doesn't believe in climate change and supports fracking.
He supports a ban on Muslim immigrants coming into the country until they put in an efficient immigration screening process. He's seen by many as a more religiously conservative alternative to Trump.
He wants the US to withdraw from the United Nations, calling it "world headquarters for the church of unbelieving humanism", and its very existence is "an affront to liberty and human dignity".
Somewhat unexpectedly, he also has some libertarian beliefs, such as supporting the decriminalisation of marijuana.
Castle hasn't actually been covered that much by mainstream media, and says this is because he challenges the status quo much more than Johnson or Stein do.
"Gary and Jill are a lot closer to the mainstream than I am," he says. "People who say they want to limit government aren't going to get mainstream press."
He's somewhat vague on a whole host of issues. He says that where Barack Obama was born is "not within my sphere of knowledge", and although he denies being a truther, he thinks there is more to the 9/11 attacks than the public knows.
