I think I know what you asked, but I'm not sure.
My ID pays homage to the Father of the Declaration of Independence - Thomas Jefferson.
Thomas Jefferson founded the Democratic-Republican Party, also known as the Republican Party.
Thomas Jefferson was a staunch advocate of American republicanism. That is what is meant by Jeffersonian democrat.
Look it up.
Unfortunately the Democratic party has changed drastically since the 50s when they were actually the working man’s party. The Republicans are no longer the party of the wealthy donors like they were back then. Both parties in Congre$$ are now mostly members of the DC Swamp only interested in preserving the Swamp.
