Why does Arizona have so many female politicians/potential politicians?

[Zioneer]

The West in general was historically a bastion of women's rights, comparatively.

Susanna Martinez is the only recent female Senator/Governor I can think of from these states: Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming. After googling it, Judy Martz, too.

Right, but those states were the first to have women's suffrage. Also the first woman in the House was from Montana.

Jeanette Rankin ran for the House before women could vote, therefore, she couldn't even vote for herself. Her brother was very supportive, and ran her campaign.

Montana passed women's suffrage two years before Rankin was elected. This article details her role in the 1914 vote for women's suffrage in Montana.

Utah passed women's suffrage while it was still a territory. In fact, many polygamous wives supported women's suffrage despite also supporting polygamy. The first female state senator in the US was Martha Hughes Cannon, who was a former polygamous wife.
