DES MOINES (AP) — When Iowa lawmakers started their legislative session this month, 35 women were among those officials reporting to the Capitol.

That matched the state’s record for women in the General Assembly, but despite increasing their numbers in Des Moines over the years, women in Iowa continue to struggle with a political glass ceiling. The state has never elected a women governor and is one of just four states to never send a woman to Congress.

Just why Iowa lags behind the rest of the country is a bit of a mystery.
