The Libertarian party has its nominee for President in 2020. It is the smart, sane, reasonable Jo Jorgensen. She is my preferred candidate among all those who will be on the ballot.
I don't think it's totally necessary to explain why, but a good start is JoJo2020's own piece Are you willing to settle for Trump vs. Biden?. There is literally nothing there that I disagree with, and no small issues I think are unimportant. Her focus is in the right place and she's got the a path forward that will help a lot of people.
There are a lot of things that could be better in America.
I strongly encourage you to vote, if you can. When voting, it's extremely important to vote for your most preferred candidate. I think even a cursory comparison will indicate that's Jo Jorgensen.
