I voted 1-6, though I think that will be made up for by one or two states moving from lean Republican to lean Democrat. New Hampshire already has, but I think Nevada and Colorado will do so by 2012.
I hope you're right. As the South moves to the right it will be important for the Democrats to do better in the West. Arizona could be critical. I think the fact that Goldwater was from that state held it in the Republican column for so long. Now McCain also, but who knows.
Arizona should eventually lean liberal, but later than Colorado and much later than Nevada. However these fast-growing, state can change so quickly!
