Andrew Romano makes an important point about the economic crisis:

Now that the press and the public are finally paying attention, Obama can't just say that McCain is out of touch and call it a day. He has to explain what he would do differently--and better. He has to sell his plan for righting an economy still reeling from the real estate and mortgage crises--something he shied away from doing today, preferring instead to rely on the "same vague... pitc[h] he has sounded over the past few months for fixing what ails the country.”

My advice: give a speech offering concrete solutions followed by a press conference. I think Obama and Biden should be giving many more press conferences. It is bizarre, to my mind, that one vice-presidential candidate has never given a national one - and we have only six weeks to go. More than bizarre: outrageous.
