Elena Kagan's credential for Supreme Court appointment

In an email, this is how Obama introduces the nomination of Elena Kagan for Supreme Court Justice:

Elena is widely regarded as one of the best legal minds of her generation -- earning praise from across the ideological spectrum throughout her career. Above all, she is a trailblazer. She wasn't just the first woman to serve as dean of Harvard Law School -- she was one of its most beloved and successful leaders, building a reputation for openness to other viewpoints and skill in working with others to build consensus. These were some of the many reasons why I selected her to be my Solicitor General, the nation's chief advocate -- the first woman to hold that post as well.

Back in April, I explained why the fact Kagan had served as dean of Harvard Law School should not impress anyone.  Today, I find it disconcerting that Obama would choose to base his case for a nomination to America's  highest court on the circumstance of a deanship.

Moreover, based on what little is known of Kagan's views on constitutional matters, consider the kind of people who would have reason to support her nomination.
