A question I haven't heard asked yet: Is Hillary's lead (and maybe win) John Edwards' fault?
The Edwards campaign has lumped Edwards and Obama together all week to try and ride Obama's coattails out of Iowa. By latching on to Obama's surge, Edwards may have siphoned some of this fabled "change vote" that everybody seems to be talking about. (After all, Ralph Nader did endorse Edwards.)
If that's the case, the Obama-Edwards fight we saw in Iowa may heat up all over again. And if Edwards really believes in change he'll pull out of the race to leave all of the change voters to Obama.
