He went on to earn his law degree from Harvard in 1991, where he became the first African-American president of the Harvard Law Review. Soon after, he returned to Chicago to practice as a civil rights lawyer and teach constitutional law. Finally, his advocacy work led him to run for the Illinois State Senate, where he served for eight years. In 2004, he became the third African American since Reconstruction to be elected to the U.S. Senate.

It has been the rich and varied experiences of Barack Obama's life - growing up in different places with people who had differing ideas - that have animated his political journey. Amid the partisanship and bickering of today's public debate, he still believes in the ability to unite people around a politics of purpose - a politics that puts solving the challenges of everyday Americans ahead of partisan calculation and political gain.

In the Illinois State Senate, this meant working with both Democrats and Republicans to help working families get ahead by creating programs like the state Earned Income Tax Credit, which in three years provided over $100 million in tax cuts to families across the state. He also pushed through an expansion of early childhood education, and after a number of inmates on death row were found innocent, Senator Obama worked with law enforcement officials to require the videotaping of interrogations and confessions in all capital cases.

In the U.S. Senate, he has focused on tackling the challenges of a globalized, 21st century world with fresh thinking and a politics that no longer settles for the lowest common denominator. His first law was passed with Republican Tom Coburn, a measure to rebuild trust in government by allowing every American to go online and see how and where every dime of their tax dollars are spent. He has also been the lead voice in championing ethics reform that would root out Jack Abramoff-style corruption in Congress.

As a member of the Veterans' Affairs Committee, Senator Obama has fought to help Illinois veterans get the disability pay they were promised, while working to prepare the VA for the return of the thousands of veterans who will need care after Iraq and Afghanistan. Recognizing the terrorist threat posed by weapons of mass destruction, he traveled to Russia with Republican Dick Lugar to begin a new generation of non-proliferation efforts designed to find and secure deadly weapons around the world. And knowing the threat we face to our economy and our security from America's addiction to oil, he's working to bring auto companies, unions, farmers, businesses and politicians of both parties together to promote the greater use of alternative fuels and higher fuel standards in our cars.

Whether it's the poverty exposed by Katrina, the genocide in Darfur, or the role of faith in our politics, Barack Obama continues to speak out on the issues that will define America in the 21st century. But above all his accomplishments and experiences, he is most proud and grateful for his family. His wife, Michelle, and his two daughters, Malia, 8, and Sasha, 5, live on Chicago's South Side where they attend Trinity United Church of Christ.
