bush announced his agenda in january 2005, but his popularity in the polls waned and his troubles mounted. continuing troubles in iraq as well as the disastrous government response to hurricane katrina led to declining popular support for bush's policies. his campaign to add personal savings accounts to the social security system and make major revisions in the tax code were postponed. he succeeded in selecting conservatives to head four of the most important agencies, condoleezza rice as secretary of state, alberto gonzales as attorney general, john roberts as chief justice of the united states and ben bernanke as chairman of the federal reserve.
