We discovered individual honey bees typically have their own preferred route and, in the vicinity of nearby landmarks, fly repeatedly very nearly the same trajectory.

That last point. Cassidy really has enormous leverage if he wants to use it. He would win this fight. Worst case is he winds up losing a primary and spends his 70s (he's 68 now) as a hero to millions. He'll likely never have as much influence over anything again as he has over this right now.
ACIP may end universal Hep B vaccination today.
Hep B prevention is Cassidy's passion, as he made clear during RFK Jr's confirmation hearings.
But let's not forget... his vote to confirm RFK Jr. got us into this mess!
He needs to use every lever of power he has in the Senate to fix it.
