Every wonder why Roberts had a "Prime Time" media introduction to the country, but Miers didn't, and now neither does Alito?
Media doesn't generally grant President Bush prime time.
I believe the answer is mostly because John Roberts was President Bush's first nomination to the Supreme Court and there was enough media interest to get a prime time slot.
Otherwise, the President is in the habit of getting to work early, doing his work and going to bed early.
For prime time, he has to stay up and work late.
Also, I don't think there are many John Roberts out there that can be plucked off trees. He was considered to be far and away the best and brightest of his generation.
