Arizona - Another state which is growing. Only has 100,000 people less in population than Missouri so will have more electoral votes. Immigration is an issue but the party needs to just win Phoenix (Manicopa County) then focus on winnning the state.
Heh, good luck carrying Maricopa. It's gone Republican in every election since 1948, and it voted 57 percent for Bush. As for my four "red states" to invest in, they would be:
Nevada
Iowa
Ohio
Florida
A generic list, but those are the most plausible states for the Democrats, along with New Mexico.
BTW, it's hilarious that Dean is wasting money in Mississippi.
