No. Miers is not a Souter
"Harriet Miers isn't a Justice Souter pick, so don't be silly. It is a solid, B+ pick. The first President Bush didn't know David Souter, but trusted Chief of Staff Sunnunu and Senator Rudman. The first President Bush got burned badly because he trusted the enthusiams of others.
The second President Bush knows Harriet Miers, and knows her well. The White House Counsel is an unknown to most SCOTUS observors, but not to the president, who has seen her at work for great lengths of years and in very different situations, including as an advisor in wartime. Leonard Leo is very happy with the choice, which ought to be enough for most Conservatives"

The most encouraging thing I've seen today was information that Miers was basically in charge of the process that gave us judges like Luttig and Brown in the appellate courts.
