WASHINGTON — The death of U.S. Supreme Court Justice Ruth Bader Ginsburg left the Texas political class in shock on Friday night. Republicans hope to secure a conservative approach to Supreme Court rulings for a generation. Trump added Cruz earlier this week to a list of prospective Supreme Court nominees, should a vacancy emerge. As it stands, most Texas political insiders — even optimistic Democrats — say Cornyn is one of the few points of stability in the Texas Republican sphere. At first blush, a Supreme Court fight could benefit both candidates.
