So the libertarian party appears to have nominated Chase Oliver. Looking at his wikipedia article, he seems to be very socially liberal, probably about as left as biden on most social issues other than gun rights. he was also the libertarian candidate in the 2022 Georgia senate election and got 2% there.
This is pretty much the norm for the LP outside of the Bob Barr aberration in 2008.
He's also openly gay which has to make him one of the first if not the first gay general election candidate ever. Googled it and all I found was Mayor Pete articles. Might have been another third party candidate at some point though.
