On a day when all other political news is going to be buried by Ted Kennedy's passing, South Carolina Lt. Gov. Andre Bauer (R) is going to make a statement at noon ET -- in which he'll call for Gov. Mark Sanford (R) to resign, the AP reports.
"South Carolina's lieutenant governor will ask embattled Gov. Mark Sanford to resign at a news conference Wednesday, a spokesman said. Lt. Gov. Andre Bauer will agree to stay out of next year's governor's race if Sanford steps down, an offer he first made in June after his fellow Republican admitted a yearlong affair with an Argentine woman."
