"The Audacity of Socialism" is available online at the newspaper's Web site.
From the introduction to the series:
Barack Obama has styled himself a centrist, but does his record support that claim? In this series, we examine Senator Obama's past, his voting record and the people who've served as his advisers and mentors over the years. We'll show how the facts of Obama's actions and associations reveal a far more left-leaning tilt to his background — and to his politics.
