If you've been following the "philanthropy can't replace government" debate (or if you haven't), E.J. Dionne has a summary rolled in here.
"The underlying fight is thus over social insurance approaches that have been part of the fabric of American life since the progressive era and the New Deal. If opponents of the ACA can discredit it, they can move on to demonize other necessary public programs — and undercut arguments for further government efforts to ease inequalities and injustices." -- E. J. Dionne Jr., the Washington Post
