We’ll all be dead by then.
That's hard to argue with.
So, I'll go fishing and enjoy myself, rather than waste time trying to replace Roberts.
Though if the goal is something lesser, like simply punishing Roberts, or annoying Romney, it might be fun enough to do. For example, if we repealed ObamaCare, maybe getting rid of Roberts would distract Romney from trying to replace it.
Ick. I feel like I'm thinking like a politician, and it doesn't feel clean.
