Possible replacements include Attorney General Alberto R. Gonzales and federal courts of appeals judges J. Michael Luttig, John Roberts, Samuel A. Alito Jr., Michael McConnell, Emilio Garza and James Harvie Wilkinson III. Others mentioned are former Solicitor General Theodore Olson, lawyer Miguel Estrada and former deputy attorney general Larry Thompson, but Bush's pick could be a surprise choice not well known in legal circles.As it happens, back in February, when talk about Chief Justice Rehnquist’s illness prompted speculation he would soon be retiring, I did a bunch of research on the people who were being named as possible additions to the Supreme Court, which includes five names on that CNN list. We need to get familiar with these guys immediately; hopefully, this will provide you with a good start.
