It's actually a great idea.
Missouri: Something has happened. There's no good reason why this state should turn red...unless we let them. It has been the ultimate bellweather for over a century. Clinton and Carter certainly got more than the big cities. Remember, this is not a out of touch state. They elected a dead guy over Ashcroft, something that didn't happen in Minnesota. We cannot lose this bellweather.
Mississippi: This is actually a very good idea. The proportion of black people in Missouri is slowly increasing. Couple that with a disproportionately large turnout, and you have 48% D. If you can get the white vote from 15 to 20-25%, this state will turn blue.
North Carolina: This state is only going to grow and become more Democratic. Pretty much everything is controlled by Dems. on a state level. Young people have really been trending Democrat and it's one of the few places in the south where you'll find Democratic white people (Asheville and Chapel Hill especially). If we can bring the white vote from 27% Dem. to 33% Dem., we've got 49+% and the state is up for grabs. The state will be larger than Michigan and just a couple 100 thousand behind Pennsylvania.
Nevada: That might be the dumbest choice, as it will prob. be ours by the next election. (we gain 2+% with every election which will bring us up just a hair under 50% but enough to win), but I guess it couldn't hurt to throw a little money in the mix.
In addition to these four, I'd be throwing resources (people more than money) at Florida, Colorado, and Virginia. We really need to be building a base in these states, because (w/ the exception of MO) they'll be growing, while the states we're currently winning won't be. To ignore the south would be fatal, as the Republicans learned a while back.
Good analysis
