When munchkin changes his party affiliation I’ll consider taking him more seriously.
Until then, talk is cheap.
If he truly wants to teach Biden a lesson, he should just resign from the Senate the day after the election - that would throw control of the chamber to the Republicans even for the lame duck session.
Or he could became an independent and leave the Democrat caucus if he doesn’t want to become a Republican (which would be best for us, too) and have the same effect.
