Last time the Democrats got control in Arizona was with Janet "Nappy" Napolitano. She spent the entirety of the state's "Rainy day fund" on all-day kindergarten. It also destroyed Arizona's state government systems in place like parks. This was because a major recession hit right after she did that (not her fault). Without the money in the rainy day fund, the state couldn't pay all its bills with the lower tax take that resulted. All state parks closed, all-day kindergarten ended, and Napolitano cast about for other sources of income.
So, she stuck speed cameras on state highways (in the name of "safety"). These became almost instantly hated. Many judges refused to hear tickets and just tossed them out. Redflex, the company running the program was found rife with corruption. This bullshit ended with her term in office.
She also saw the longest prison hostage situation in Arizona's history, one where a female prison staffer was held hostage and repeatedly raped. She refused to make a decision on this that could have ended it beyond negotiation.
She also vetoed more bills than any Arizona governor in history (Republican legislature). So much for cooperation and working together.
Basically, Napolitano was the worst Arizona governor we've had in recent history, by far.
She served one term, and knew she wasn't getting reelected. Obama made her Secretary of Homeland Security and she fucked that up too.
