That's not a swing state. Georgia barely is.
Arizona is a little complicated, but is very much a swing state. We have had both R's and D's in top positions over time. The state legislature is very evenly split. If one member breaks rank it can change the outcome on an issue.
State media emanates from Central Phoenix and is very, very blue. Coverage is heavily biased. This came home for me during the Maricopa County audit. There was a group of 15-20 people yelling insults and threatening workers entering and leaving the arena. I thought it was a protest group. When I asked who they were, a security guard told me that was the local media entourage.
We also have strong forces from out of state working to change the makeup of Arizona because it is always near a tipping point. We have volatile ballot measures every election that are sponsored by national groups using a local "organization" as a front.
Arizona is a red state with a big purple city. Maricopa County is red outside of Phoenix. The population is largely centered in Phoenix and Maricopa County, which accounts for over 60% of voters.
The biggest reason for the split is the division among conservatives. The Democrats are very singular in voice and live by a mantra of doing whatever it takes. They will run Democrats in Republican primaries to confuse voters.
Conservatives are divided into neocons and populists. The neocons, or McCain Republicans, are backed by old money. They will not tip the boat and tend to run unpopular candidates with large bank behind them.
The populists have greater numbers, but no organization or financial backing. They lack good candidates, because you must be willing to run against the machine and good luck getting funded. If the Republicans here were organized and strategic, there would be no swing state.
