Amy Sullivan gets it right ...
She warns the presidential candidates against saying yes to a forum hosted by Rick Warren. Here reasons for being skeptical are, I think, valid:
The McCain-Obama forum was, I thought, slanted heavily towards McCain. Unless the President knows something about a change of heart in Rick Warren that the rest of us don't know, I would expect this one to have a similar slant. Everywhere I look, a politically conservative Evangelical has more sympathy with a politically conservative Mormon (or Ayn Randian, for that matter) than with a fellow Christian who is, like Obama, moderate - and even less with a progressive.
