Chuck at Just a Bump in the Beltway is opposed to Alito because of a memo he wrote when he worked for the Reagan administration:
How many more "smoking guns" do we need before the Dems and anyone interested in protecting a right to privacy/choose stand up against this guy?
While I understand Chuck's concern that Alito may one day overturn Roe v. Wade, I'm not comfortable with the idea of opposing his nomination because of the memo. Lawyers are advocates for their clients, and Alito's client in 1985 was the anti-abortion Reagan adminstration. Alito was just doing his job, and that fact shouldn't be held against him. Similarly, if a lawyer defends a murderer, it doesn't mean he's in favor of murdering people.
I like Alito a lot more than Harriet Miers who was abysmally unqualified for the job. Bush picked her because she was an evangelical Christian and presumably supported all those far-right Christian views. Alito is less likely to overturn Roe v. Wade than Miers would have been.
If Alito's nomination were somehow stopped (not likely at this point), Bush would only nominate another anti-abortion "stealth" candidate, and I prefer Alito's long record of public service and his reputation for being very smart and conscientious over another unqualified stealth nominee.
