Does 0bama expect Kagan to provide more forthright testimony than a SCOTUS with judicial experience?

"Harriet Miers has had a distinguished career as a lawyer, but since her experience does not include serving as a judge, we have yet to know her views on many of the critical constitutional issues facing our country today. In the coming weeks, we'll need as much information and forthright testimony from Ms. Miers as possible so that the U.S. Senate can make an educated and informed decision on her nomination to the Supreme Court." -- Barack 0bama, 2005
