Virginia Postrel writes about the National Cowgirl Museum and Sarah Palin's example:

Full of inspiring role models, the museum presented a piece of feminist history that gets left out of the city-oriented accounts most of us learn. There's a reason Wyoming was the first state to let women vote and that the first female Supreme Court justice (a member of the Cowgirl Hall of Fame) came from Arizona. The thinly populated western frontier couldn't afford to waste women's talents (though Arizona and New Mexico were among the last states to give married women full property rights).

Actually, New Jersey was the first state to grant women suffrage, at its inception. It was revoked in 1807. Wyoming granted it as a territory in 1869 and then kept it after it became a state in 1890.

Wikipedia conveniently fails to mention the important role of the Republican Party in achieving women's suffrage in the United States, and misrepresents the role of President Woodrow Wilson, a Democrat, in passing the 19th Amendment. Wilson opposed it vigorously until 1918, even to the point of putting suffrage demonstrators in prison, before buckling under and supporting women's suffrage - something that was first advocated in the Republican Party platform 46 years earlier.

And of course the first woman elected to Congress was Jeanette Rankin, Montana Republican, in 1916.
