“Where the hell is W? Where the hell is Cheney?! Powell? Rice? How about Obama?!”
Can’t speak for the others, but Powell is likely saying “Yes, I’m a Republican, but the Republican Party is a bit rough around the edges.”
Nope. We won’t hear from Powell until about July 2024 when he will do multiple TV interviews claiming he’s a Republican but simply cannot vote for Republican presidential candidate X, because... reasons. Like clockwork.
