Which McCain states will the Obama campaign target?

Missouri, Georgia, and Montana are obvious because they were close in 2008. Arizona looks closer than one would expect for a State that has a Favorite Son, so it is on the list -- if only because of the open Senate seat.

Open Senate seats will attract his attention.

Also, Missouri and potentially Indiana will have competitive Senate races where turnout in St. Louis/Lake + Indianapolis could help whether or not Obama wins the state.

So long as the Tea Baggers don't knock off Dick Lugar in the primary, Lugar is as safe as they get.  If the Tea party types do knock off Dick Lugar, then the US Senate seat from Indiana becomes competitive, but I wouldn't bet on that circumstance.

Missouri will have a competitive Senate race unless the GOP nominee melts down catastrophically.
