I had to look him up. Per Wikipedia ...
He is the star, executive producer, and creator of Funny or Die's Billy on the Street, a comedy game show that aired on truTV from 2011 to 2017. He also did a Bravo web series called My Life on the Z-List: Jen's Vlog that was an online companion to Kathy Griffin: My Life on the D-List. Eichner is Jewish, homosexual, and a Democrat.
On February 1, 2018, Eichner announced a new initiative called Glam Up the Midterms, during that night's episode of Jimmy Kimmel Live!, with the support of several late night hosts including Sarah Silverman, James Corden, Seth Meyers, Jimmy Kimmel, Conan O'Brien, John Oliver, Chelsea Handler, Robin Thede, and Andy Cohen. Glam Up the Midterm's purpose was getting people to vote in the November 6th midterms, especially millennials, of whom only 12% voted in the previous midterm election. Eichner joined the progressive political organization Swing Left as senior advisor starting in 2019 and endorsed Elizabeth Warren in the 2020 Democratic Party presidential primaries.
"Glam Up the Midterms," eh? I suppose that is why Eichner played himself in the "Cher: The Unauthorized Rusical" episode of RuPaul's Drag Race back in 2018.
Hmmm ... I can see why no one knows who this nobody is.
