This article from today's LA Times is an excellent summary of the pattern and jurisprudential practice of Judge Sam Alito. He is a corporatist and Bush has absolutely no mandate to place him in a lifetime position on the Supreme Court.
I say this even if he upholds Roe v. Wade. Alito will cause far more harm to all human beings with his judicial activist stances on standards for the burden of proof in civil rights and other simliar cases--and his inability to understand the proper and original scope of Congress' powers to enact economic legislation and the scope of the commerce clause.
