I seriously doubt a democrat would cross over and vote for a Republican and any Republican that crossed over to vote for a Democrat would end his career immediately.
Eventually a Republican will be voted in as Speaker, maybe its Kevin McCarthy maybe it won’t.

I could see a couple doing that, e.g., Manchin. They don’t want a GOP, but can live with McCarthy. After all, he’s voted with them often, selling out our side. They might think the devil they know is better than the devil they don’t know. He’d be better for them than someone more conservative.
