What if the second Chief Justice of the US Supreme Court doesn't get sick during his journey over the Atlantic in late 1800? The main reason he stepped down from his position of Chief Justice was this sickness, so he'll stay on. As a consequence, John Adams won't be able to appoint John Marshall as the third Chief Justice. When Ellsworth finally does step down, it will be Jefferson appointing his replacement. How does no Chief Justice John Marshall change history? Who will Jefferson choose as the next Chief Justice?
