We don’t know exactly what this means — other than women are 50 percent of the population and they’re under-represented in the Idaho Legislature and across the nation — but the raw numbers look like this.
Idaho House: 56 Republicans and 12 are women = 21.42 percent
Idaho Senate: 28 Republicans and 6 are women = 21. 42 percent
Idaho House: 14 Democrats and 6 are women = 42.85 percent
Idaho Senate: 7 Democrats and 3 are women = 42.85 percent
