It takes 2/3rd’s of Congress to pass an amendment so no he can’t make his party do it. He’d have to convince about 1/3rd of the GQP to do it too. Remember this is the party that stole 2 seats and just finished successfully weaponizing the courts to push their policy agenda as the out party. You think a single one of them wants to term limit boofer or the handmaid?
Or he can somehow as president spend all his political capital not doing president things and instead push it at the ballot level state by state, which if he was lucky would’ve taken likely his entire term. He also inherited the Covid economy with the Delta variant ripping through the country the moment he took office so “SCOTUS term limits” wasn’t exactly being prioritized over, quite literally, millions dying.
I am very critical of Biden but sometimes y’all have the most ridiculous suggestions for what he should’ve spent his time doing that shows very little grasp of what the executive branch actually can and can’t do, both technically or practically speaking.
