election 2008: what about the military commissions act of 2006?

From Wikipedia:

The United States Military Commissions Act of 2006, Pub. L. No. 109-366, 120 Stat. 2600 (Oct. 17, 2006), enacting Chapter 47A of title 10 of the United States Code, is an Act of Congress (Senate Bill 3930) signed by President George W. Bush on October 17, 2006. Drafted in the wake of the Supreme Court's decision on Hamdan v. Rumsfeld, the Act's stated purpose is to "To authorize trial by military commission for violations of the law of war, and for other purposes." The bill limits captives' access to habeas corpus and has been suggested to be unconstitutional.

Of the four presidential candidates who voted on this bill, only one supported it. I haven't been able to track down opinions from Romney or Giuliani, but it's probably safe to assume that they're aligned with McCain.

John McCain: Yea
Hillary Clinton: Nay
Barack Obama: Nay
Ron Paul: Nay

Senator Patrick Leahy on the MCA:

"Passing laws that remove the few checks against mistreatment of prisoners will not help us win the battle for the hearts and minds of the generation of young people around the world being recruited by Osama bin Laden and al Qaeda. Authorizing indefinite detention of anybody the Government designates, without any proceeding and without any recourse -- is what our worst critics claim the United States would do, not what American values, traditions and our rule of law would have us do. This is not just a bad bill, this is a dangerous bill

Senator John McCain on the MCA:

"Simply put, this legislation ensures that we respect our obligations under Geneva, recognizes the President’s constitutional authority to interpret treaties, and brings accountability and transparency to the process of interpretation by ensuring that the executive’s interpretation is made public. I would note that there has been opposition to this legislation from some quarters, including the New York Times editorial page. Without getting into a point-by-point rebuttal here on the floor, I would simply say that I have been reading the Congressional Record trying to find the bill that page so vociferously denounced. The hyperbolic attack is aimed not at any bill this body is today debating, nor even at the Administration’s original position. I can only presume that some would prefer that Congress simply ignore the Hamdan decision, and pass no legislation at all. That, I suggest to my colleagues, would be a travesty."

President G.W. Bush on the MCA:
