Nancy Pelosi

Speaker of the House Nancy Pelosi is the first woman in American history to lead the House of Representatives on Capitol Hill.

She's a San Francisco Democrat who has called President Bush a "total failure" and wants American women to "know their power," as her new book says.

She's been tough with the gavel, relentless on blasting the Iraq war, and challenged by the rising strength of "blue dog" conservative Democrats.

But her biggest challenge may lie ahead, if the Democrats win it all — Congress and the White House.
