It’s clearly Stan he doesn’t rip on him as much as he rips on Kenny and Kyle

Easily Stan.

Stan obviously.

“I hate you Kenny”

-Cartman

How does Kenny have more votes than Stan? That's crazy. Plus I really don't think Cartman even hates Stan at all.

Hmmm...

Cartman used to hate Kenny in the early seasons, before Kyle took his place. He seems more of less indifferent towards Stan.

Stan without question
