Pro-Choice Senator Must Back Bush -Senate Leader

Pro-Choice Senator Must Back Bush -Senate Leader: "WASHINGTON (Reuters) - A Republican senator who has questioned whether an abortion opponent could win approval to the U.S. Supreme Court must agree to back President Bush's nominees if he is to head the committee acting on those nominations, the Senate's Republican leader said."

Partisan politics aside, how is a chair who will automatically back a president's nominee in any way superior to one who will automatically oppose an anti-choice nominee?
