Easy:
- Pick a senator like John Kyl, Jeff Sessions, or Orrin Hatch
- Pick a former senator like Fred Thompson
- Pick the former Solicitor General, Ted Olsen
Any of these would be easily confirmed, and all are reliable conservatives.
Are you so sure? Hatch? A reliable conservative? His name has been mud on this site many times.
Somehow, despite my earlier prediction of a legal scholar, I have a hunch this could be the guy. There's a sympathy factor there (due to the death of his wife on 9/11) that no other nominee would have, and it would be a massive advantage to nominate someone about whom the Dems would have very little luck attacking without appearing cruel.
