As far as I can see McCain has no plan except more of the same.
Obama has plans, but they will necessarily include some kind of tax increases...which he will cal "sacrifices" during the campaign. For the GOP to win they will have to go negative fast and tag Obama as a a re-packaged "tax and spend liberal." Then they will get the down and dirty "independent groups" to keep the "He's a muslim" and Rev Wright issues stoking (No one asks how a muslim can also be a follower of a "christian" pastor).
SO for Obama the name of the game is to not let them define him before he can define himself.
