The January scheduling of Judge Samuel Alito's confirmation hearings for the Supreme Court, instead of December as desired by President Bush, was caused in part by political needs of Republican senators facing opposition for re-election.
Sens. Jon Kyl of Arizona and Mike DeWine of Ohio are supporters of Alito. But each wanted to get home in December to prepare for strong Democratic challenges.
