I think this critique of Hillary's experience is going too far.
The re-emergence of Bill Clinton on the international beat for America would be a good thing. The wealth of experience and understanding only a trusted word away from the Presidency is probably more than Obama can manage.
If Maureen Dowd is worried about experience on foreign policy (and shouldn't we all be, quite a lot?), she should be looking at Dodd and Biden, both of whom have more than Obama, who has not been involved in national politics except for a short while.
