Who else would it be? Certainly not Biden. Heck, I'd be surprised if he can make it through the first two years of his term. He'll lateral to Harris who'll use the Presidential pulpit to ride into 2024. If they time it right, she'll be eligible for two full terms.
Who do you think the Republicans can conjure up to oppose her? The Republican party is killing itself right now. People like you are killing it. .
Maybe by Harris's first midterms the Republicans can unify to take back Congress and, in 2028, the WH.
Trump can beat her. He is the Republican party. Rove is irrelevant to Trump's base and that is the base of the Republican party.
