Running for president as a Libertarian Party candidate is about playing spoiler to the Republican and Democratic nominees - not about making a serious bid for the White House. That's why Stephen Colbert asked the 2016 Libertarian ticket which campaign they'll steal more support from this fall - Hillary Clinton's or Donald Trump's - when they stopped by The Late Show on June 9.

"I think more from the Rs. There's a lot of Rs out there that haven't signed on with Trump yet," said Bill Weld - the former Republican Massachusetts Governor turned Libertarian VP candidate.

His running mate - former Republican Governor of New Mexico Gary Johnson - disagreed. "In all the polls that we've been in...there have been more votes [diverted] from Hillary, to this point. But I think when all is said and done, it will be equally from both sides."

Both candidates have embraced their role as presidential outliers. They've both been successful governors in a conservative party, but they've both taken "fringe" positions for Republican politicians. Johnson has supported repealing marijuana prohibition, and Weld endorsed gay rights and legalizing medical marijuana.

Libertarians embrace mainstream American values

Besides, Johnson says their supposedly fringe party embraces values shared by most Americans. They're fiscally conservative polticians who believe in enhanced personally liberties for gay and lesbian Americans, women, and people who want the right to legally smoke marijuana. He says these are mainstream values, not fringe ones.

And they aren't counting out their presidential bid just yet. "We wouldn't be doing this if there weren't the opportunity to actually win," Johnson added. "But we've got to be in the presidential debates to make that happen."
