I think Harris will announce that at her next press conference.
Issues and other points on which candidates do not differ are irrelevant to determining who to vote for.
You seem pretty convinced that Chase Oliver is fully qualified to be president of the United States. Voting for him is not a protest vote for you, since you said in another post that it is equally possible that he could win Illinois as that Trump could win it. So, a question or two about how he differs from the candidates put forth by the Republican voters, and the Democratic Party bosses:
President Trump has been a self-made millinaire, but there is no history of him ever resting on those laurels. He has run huge companies, produced television shows, and was president for a full term, during which the border became more secure and black unemployment was at its lowest in history.*
Vice President Kamala Harris, for all her faults, has been a big city district attorney, the attorney general of a mega-state, a senator from that state and a nearly full term as Vice President. She was elected to each of those positions.
What government experience does Chase Oliver have?
What elections has Chase Oliver won?
Outside of any government jobs, what private sector jobs has he held?
The previous Libertarian candidate for president was a psychologist. I'm a teacher, you're a Marine and whatever you do now. What is Oliver Chase' profession or trade?
