The biggest recent example was VP Harris going before WV local news stations and very loudly questioning why he didnt support the $1400=2000 checks as part of the stimulus program. That flipped him pretty quickly.
That said, I dont really know how much leverage the Biden admin could meter out with the PRO act wrt Manchin's base, as the Union leadership would have to be the ones directing most of the questioning.
How? Like the other user said, if Biden denounced Manchin, that'd probably help Manchin.
