I mean, the votes are still being counted - so the facts aren't all in yet. A Democratic Senate is at this point only a projection, not a sure thing.
And there is some oversimplification. For instance: Ron Johnson and J.D. Vance, both close Trump allies, won their Senate races - WI is a battleground, though I consider OH a solid red state at this point, so the Trump factor is less impressive there.
But I do think this tells the broad story. To the extent the meme ends up being wrong, shame on me!
