Registered Libertarians? there are a few. I might add more capable than both Trump or Biden IMHO.
most of the effective "libertarians" are just leaning but still call the GOP home & I don't see that changing. They almost always stop short of labeling themselves one, with one exception, Justin Amash.
I believe he is/was the best shot at legitimacy & a very capable leader. Not sure, but there seemed to be some (understandable) blowback from the majority of the party due to his late entry & some behind-the-scenes stuff probably led to his dropping out. He is still fully committed to the party & I predict a strong presence/run in 2024. Of course, that could be even more of a mess if Rand Paul decides to throw his hat in the ring as well considering he has some libertarian support (& the GOP backing him). he would probably be the favorite.
As for current, card-carrying libertarians? Jorgensen has a nice platform but I just didn't like the vibe during the debates. that said, she was light years ahead of VS, Hornberger stopped campaigning & focused solely on attacking Amash (it was a bad look) & Larry Sharpe (another potential candidate) was only interested in VP at this time. Kokesh was just too radical & abrasive. Jorgensen does have the right idea when it comes to legalization, protection of privacy, Criminal Justice Reform, & foreign policy. She seems very capable, just inexperienced. I don't like how often she plays the female card though. She has my vote.
Spike Cohen (free ponies, mandatory toothbrushing, zombie power, etc) won the VP nomination over Sharpe (decentralization of education, legalization, criminal justice reform) this year. there is obviously still alot of work to be done.
I love the party & identify most as a libertarian, but they really need to get their shit together. it's one step forward, two steps back. I was really hoping Amash would change the direction of the party THIS year. Both 2016 & 2020 were ripe for a legit 3rd party run.
FWIW, the party has been gaining seats in local elections &, IMHO, It could be a major force if/when Rand Paul & Thomas Massie stop playing nice with the GOP & follow Amash's lead. it's now the party of Trump & no longer moving in the direction of liberty. one can hope.
