Cruz heartily endorsed Roberts. Check the National Review article he wrote when Roberts was nominated.
Clearly the lesson learned is to go for the fighter, like Scalia, Thomas and Alito.
What are you going to do after the President makes his selection? No one else has that responsibility. Once nominated, what would you have done in Cruz’s position?
Oh, and don’t forget to point to your own prescient take on Roberts, pre-confirmation. I was as disappointed as anyone at the ACA votes, but on what information were you predicting them in 2005?
