...But the nomination is made and we'll now have to see if we're stuck with an activist. If not, great. If so, it could be a very long and damaging 30 year wait to replace him....
Be positive. If he's a closet commie, we end almost immediately. There won't be any thirty year wait.
We end how? The only grounds for impeachment are not being in "good behavior". We had a Senate that couldn't impeach a President for committing a felony in office. We have a Senate who didn't have the spine to deny Arlen Specter the Judiciary chairmanship. Do you think there would be any hope of removing Roberts because he "pulls a Souter"? This is why the NOMINATION process is important. Once confirmed he's in regardless of whether he turns out to be a closet activist. Done deal, at least in this universe.
