Newt is on his game.
An old politico, been thru every power move, scandal, potential scandal, damage control, cover move, etc.
Sharpened by the knife-on-knife action. Had some years out of the limelight and office to regroup and reflect.
He’s now an old lion, much like Churchill, back in the game with the experience and wisdom that comes only from trench warfare, but with the redeeming grace that comes from finally (we all fervently hope!) of rising above it, lessons learned.
He has a short time to redeem himself- he seems to understand that now and has found himself and his calling and is meeting it.
That can resonate!
Your reference to Churchill is spot on. After years “in the wilderness” Newt seems revived and ready to split some heads.
