The battle continues over the confirmation of President Bush’s nominee for chief justice of the Supreme Court, John Roberts, as more prominent Democrats have made their voting intentions public ahead of today’s vote. Senators John Kerry and Ted Kennedy say they will vote against Roberts, while Vermont Democrat Patrick Leahy says he will support Roberts. Earlier this week, Minority Leader Harry Reid said he would vote no. Meanwhile, the chair of the Senate Judiciary Committee, Pennsylvania Republican Arlen Specter, is calling on President Bush to delay nominating a replacement for retiring Justice Sandra Day O’Connor. Specter said he talked to Justice O’Connor about staying on the high court and that “She’s prepared to do that’’ through the court’s term ending in June. But Senate Majority Leader Bill Frist said he urged Bush to submit a name to the Senate right away.
