Revealing portraits of the two front-runners, here and here.  (The latter is mostly about Bill, but since Hillary’s main claim to pertinent "experience" grows out of her marriage to the former President, it is surely relevant about what her actual policies are likely to be.)  Of course, neither may be front-runners for long, given the increasing support for Romney in Florida, and Clinton’s trouncing in South Carolina and now, it appears, Senator Kennedy’s expected endorsement of Obama.
