Calling them "lawmakers" at this point seems like a stretch given our laws are now almost exclusively dictated via social media/EO by the executive. I wish I was kidding. Maybe "former" or "legacy" lawmakers is more accurate?
Lawmakers in name only. Rubber stamping bills proposed by lobbyists and the executive branch. Lino printing
atp calling them show-uppers would be a little bit much. perhaps "elected vacationers"?
legacy seems appropriate given their average age
Maybe call them "chat", like a Twitch chat? Trump is already streaming from the Oval Office and blogging on Truth Social, and the chat reacts within the allowed boundaries.
