From NBC News on March 24:
"As the Republican Party grapples with a potential Donald Trump nomination, third parties - especially those with established infrastructures and widespread ballot access - could become an avenue for alternatives.
"The split in the Republican Party over Trump's candidacy has opened up a wide range of possibilities if a deep divide among Republicans continues to grow. A third party candidacy by a well-known establishment figure is one of those possibilities, and the Libertarian Party, which shares some philosophical ground with the GOP, would seem to be a natural fit.
"It's the one third party in the best position to compete in a general election. It's currently on the ballot in 32 states and is the only third party that has a chance to be on the ballot in all 50 states and Washington, D.C. in November."
