Need to Know, October 1, 2010

This week on Need to Know: There’s the campaign, and then there’s the shadow campaign. A Supreme Court ruling has unleashed a tide of special interest money in this year’s midterm elections — and the vast majority of it is hidden from public view. In this week’s edition of The Watch List, we tell you what you need to know about the new rules, and talk to Peter Stone of the Center for Public Integrity about how the influence of money is warping this year’s crucial House and Senate races.

Then: Dr. Emily Senay examines two conflicting reports about the use of mammograms in breast cancer detection, and tells us five things we need to know about how the controversy affects health policy. Jon Meacham talks to Daniel Ellsberg, the man behind the release of the Pentagon Papers 40 years ago, who was dubbed “the most dangerous man in America” by Henry Kissinger. And as a new film about the origins of Facebook generates buzz, we explore what it takes to disconnect from the social network — and what happens to those who get sucked in.

Watch the individual segments:
