Karl Rove will become a deputy White House chief of staff in charge of coordinating policy between the White House Domestic Policy Council, National Economic Council, National Security Council and Homeland Security Council. He has been a senior advisor to the President, and responsible for expanding the Republican base, one might say. Although he has been involved in policy matters, this will solidify his authority (as if he needed more solid ground upon which to stand!), and proves that Bush is serious about his agenda, including Social Security.
