Best summary I've seen:

he's a Peter Thiel creation, it doesn't take a lot of research to see this. He's basically been on Peter Thiel's paycheck for like a decade iirc? He's made millions working directly and indirectly for him. It's not even particularly subtle. Thiel made substantive donation to non-profits that existed soley to help get Vance elected etc...

took me like 2 google searches to get to reasonable sources for all that, without Thiel you wouldn't know who Vance was

There's not much to it. He's distinctly unlikable, and he's also really easy to meme about.

Ongoing memes that I know:

• Vance fucks couches - afaik this never happened but people like to say that it happened anyways because it's funny
• "Have you ever said thank you"/clown suit - taken from a meeting between Trump and Zelenskyy. Vance interjected and asked Zelenskyy if he had ever said thank you to the aid that the US has given to Ukraine. Vance also asked why Zelenskyy wasn't wearing a suit. Apparently the Ukrainian word for suit is the same as a clown suit, so people like to say that Vance asked Zelenskyy to wear a clown suit
• baby Vance - I honestly don't really know where this originated from, but people just edited his face to make his face small.
• killed the pope - the pope died the day after meeting with Vance. People like to say that his evil caused the pope to die. As an interesting side note, the pope supposedly wanted to teach Vance about compassion shortly before the meeting

You should research about Curtis Yarvin and understand that Vance is a follower of his work. There's a good Behind the Bastards two-parter on him.

he fucked a sofa and wrote about it.

You could watch the Ron Howard directed biopic Hillbilly Elegy based on his memoirs. I think the director's cut has the couch fucking scene and a few other extras.

Nothing. Ignore chump America
