It is not any use to replace him. There is no Representative that can withstand the threat that a new Speaker will receive for the FBI to “find” child porn on his cell phone or home computer. Placing such files on a device is the easiest thing in the world. Defying that threat would just get the Speaker arrested and jailed and convicted of possessing child porn and render him unelectable and ineffective if he were not convicted. The Congress is entirely at the the whim of the PTB.
At this point, it’s rearranging the deck chairs on The Titanic.
