I mean, this is a cute meme. But it does seem to illustrate why playing dirty scores points while playing "by the rules" is for chumps and suckers.

Vance is a very effective sleaze. His smear of a migrant community in his home state has been devastatingly effective at stirring up a lynch mob. People are casually rejecting any semblance of truth, because "Black man ate my dog!" is this statement that resonates among his supporters and among the ambient racist fucks that are looking for someone to pander to them.

Calling him a couch fucker appears to have a better track record at deflecting his racist critiques than trying to get to the "truth" of his bigoted remarks. It forces him back on the defensive and alienates him from those same racist fucks to which he's looking to gin up turnout.
