I agree, and here's my preferred scenario:
1. Roberts is nominated and confirmed.
2. Rehnquist retires.
3. President Bush nominates Clarence Thomas for Chief Justice.
4. President Bush nominates Janet Rogers Brown to fill the vacant seat.
5. We pop some popcorn, sit back, and watch the Democrats' heads explode.
That's a pretty good scenario.
We may not have to wait this long, I think if Rove were to give them a funny look, they might explode now.
