If a nomination is based on solely writing or framing an opinion, Miers is eminently qualified. Miers said she respects the rule of law and the Constitution. If one had to go on that facet alone, she's eminently qualified, especially in the current climate of "judicial tyranny", given how the judicial branch has shredded parts of the Constitution, stifled the "will of the people", and created more problems by overstepping into the legislative branch's territory by legislating from the bench. Her opinion would be the tipping point of alot of these 5-4 decisions.
The White House can put the most positive spin on this nomination, it won't change the fact that they're nominating a profoundly weak candidate from a position of extraordinary weakness.
