In campaign news, speculation is intensifying over who Senator Barack Obama will pick to be his running mate. On Thursday, Obama announced that he has decided on a vice-presidential candidate but declined to provide a name. Obama said, “I want somebody who’s independent, somebody who can push against my preconceived notions and challenge me so we have got a robust debate in the White House.” Obama is expected to announce his decision today or tomorrow by sending a text message to his supporters.
