Could anti-Trump conservatives go Libertarian?

Now that Donald Trump is the presumptive Republican presidential nominee, anti-Trump conservatives are casting about for a third party alternative. Retired Gen. James Mattis has already turned them down. Names like Mitt Romney, Nebraska Sen. Ben Sasse and retired Oklahoma Sen. Tom Coburn are still being floated.

Could the Libertarian Party be a possibility? Unlike a hypothetical new party, the LP actually exists and has been around since 1971. Libertarian presidential candidates usually get on the ballot in all 50 states or close to it. There are already people running for the party’s nomination.
