The only real question was how would Alito perform in this venue. On a substantive level, the issues and answers have already been reviewd and analyzed.
Alito is doing fine, and will do fine. He has no secrets to hide - he's being honest, and he understands the issues on many levels. IOW, he won't get tripped up - there's nothing to trip on.
Even mock trials or debates would be better than the circus the dems are running. How do you feel Alito did on the Vanguard question? Of course Alito never got to finish answering Olds surfer's question on the ten year-old... but got in enough I feel.
