OCCUPATION: Speaker of the U.S. House of Representatives
PREVIOUS APPEARANCES ON THE TIME 100: 1
PRO: With a Democrat in the White House and a majority on the floor, Pelosi has been able to shepherd a slew of new legislation. And for the first time in years, Congress's approval ratings are poor to middling, rather than abysmal.
CON: She's become a favorite target of Republicans, many of whom blamed the bailout bill's initial failure on supposed partisanship.
