As the election nears, thousands of people are signing up to "trade" their votes.
Here's how it works: A Gary Johnson supporter in a swing state like Ohio can promise to vote for Hillary Clinton. In exchange, a Clinton supporter in a strong blue state like California would promise to vote for Johnson. Voila! Both get to make sure their votes count while staying true to their principles.
It's not a new concept, but a number of online marketplaces are springing up to make it easier to swap votes. And the growing movement could make all the difference in a tight race.
Two of the biggest vote trading platforms that have sprung up during this election are #NeverTrump and TrumpTraders.org. As of Sunday evening, they said they've facilitated the trading of over 50,000 votes combined, and more than 12,000 in key swing states.
Silicon Valley entrepreneur Amit Kumar is the founder of #NeverTrump and says the response has been overwhelming. He says the pace of signups quickened over the weekend and people have been using the app in real time while in line during early voting. "People are coming here and finding strangers," Kumar says. "From California to Florida. From Facebook to Instagram to Twitter, people can connect. It's been crazy."
