Funny to think that there's a very real chance that no living president or vice president will be voting for the Republican candidate this race. Even the living Republicans - W Bush, Cheney, Pence. Hell, even Dan Quale probably won't (considering he advised Pence to certify the 2020 results). And as for past living GOP presidential candidates (e.g. Romney) they probably won't be either.
If you would have told any Dem in 2002 they'd be voting for the same person as Cheney in 2024 but it wouldn't be a Republican they'd say you were nuts but here we are.
Remember, people: There is no way to prove whether or not he will actually vote for Harris. It's easy to say that if you're just looking for attention because there's no way to prove if you're lying.
