Obama cannot afford to reveal certain plans 'ahead of time' if he wants to win.
so I believe he is SAVING alot of substantive policy 'specifics' for the one-on-one debates with McCain in the future.
Once he 'tips his hand' the Republicans will go on the attack:
1. First they will try to criticize / debunk any solid ideas.
2. While trying to steal them at the same time so that they can claim they 'came up with the idea first'.
They are like those students who 'peek over your shoulder' to cheat on an exam...
IMO, if you are looking for something
'that works for you' you should definitely tune-in once they take the stage together.
Stay tuned.
