But if you look at it right, once someone has been made a Supreme Court judge why would they need his patronage any more?
Exactly, they wouldn't! DH and I were talking about how 'fun' it would be if Gorsuch and Kavanaugh 'turned their coats' now they're on the SCOTUS.
Scrotus' only 'weapon' now would be to dig up dirt on them and threaten exposure. But even that wouldn't actually remove them, it would just embarrass them and/or hold them up to ridicule.
To actually remove, they'd have to be impeached. Only one Justice has been impeached by the House (Samuel Chase) but once again, the Senate did not vote to remove him from the bench.
