6. Peter Orszag
Job title: Director, Office of Management and Budget
The White House budget director is the youngest member of Obama's cabinet and a powerful voice behind health care reform.
Orszag, who crafts the federal budget, says he doesn't like to get involved in politics. But since health care is one of Obama's top priorities, the Princeton and London School of Economics grad has supported the Senate Democrats' plan and said health care reform doesn't increase the federal deficit--in fact, it can shrink it.
