When word broke last night that Joe Lieberman had taken the health care bill hostage and that it appeared the White House and Senate Majority Leader Reid were ready to cave, progressives howled. The process by which one so-called centrist can make unreasonable demands to get a bill passed has many calling for dumping the filibuster, and activists wondering what they can do. Is it time to oppose the health care bill? Is the public option well and truly dead? And how the heck did Joe Lieberman, party of one, wind up in charge? Jacob Hacker, the "father of the public option," and Stanley Resor Professor, Department of Political Science at Yale University, Maggie Mahar, editor of HealthBeatBlog and author of Money-Driven Medicine: The Real Reason Health Care Costs So Much, and Luke Mitchell, senior editor at Harper's magazine, join us to try to explain what's left in the bill and what's likely to happen next.
