I get what you mean, because it’s that thing that I’ve been unable to encapsulate into a single word or anything, but:

“Biden/Kamala is so right wing, there’s no way the Republicans can accuse them of being a communist!”

Republicans call them a communist anyway

“Ah! Well, nevertheless…”

I also do think that capturing Republican voters is that one white whale they’ve been chasing for a long time, though.
