On Tuesday, the former Arizona governor told reporters that she is confident her home state will take after Nevada, New Mexico and Colorado in gaining Democratic voters in the coming cycles.

“Arizona will be behind them,” Napolitano said during a discussion hosted by the Christian Science Monitor. “I think it will be more purple over time, but ultimately blue.”

In 2012, Sen. Jeff Flake, R-Ariz., secured his first term with a 3-point margin of victory in a race much closer than many operatives anticipated. Meanwhile, partisan control of the congressional delegation flipped as Democrats won two House seats and Republicans lost one seat. But those gains were also a reflection of a newly redrawn congressional map that favored Democrats.

“It’ll happen, I think,” Napolitano said. “The fact that I could win three straight elections there, I think is indicative that Democrats can win and do win in Arizona.”
