The states that have had female senators, color-coded by party (NC being the only state to have elected women from both):
The states that have had female governors, again color-coded by party, although NC is turquoise for some curious reason known only to Wikipedia:
However, a lot of these women have been appointed, usually when their elected husbands died. This typically happened in the dark old days, which is to say, from the period when the earth cooled until approx. 2002. In fact, of the 37 women ever to have served in the US Senate, only 23 were elected in their own right. Of those, 16 are there today. (Would be 17 out of 36 if Hillary were still there).
These are the states that have elected women to be governors-or-senators, both or neither.
Not much of a geographical pattern. I have to say I’m surprised about Alaska. Its politicians tend to stay in office forever and it’s only been a state for 50 years (same goes for Hawaii, on both counts) but it has Gov. Tina Fey and Sen. Lisa Murkowski–appointed by her dad but then later elected. Say what you will about Sarah Palin, but there are very few women who have been elected to high office without being related to a powerful male politician. (Todd’s relationship to the Alaska Independence Party notwithstanding).
Almost every state has elected women to the House. The exceptions are mostly tiny states with few congressional districts, such as Vermont and North Dakota. There are only two states that never, ever had a woman serve as a governor, a senator or a representative: Mississippi (shocker) and Iowa (shocker; non-sarcastically). But both have had female lieutenant governors, and that’s the real money-maker.
On the other end, both Maine and California have two female senators. Maine is the only state to have elected three women to the chamber. And California has Nancy Pelosi, too. Washington State is a goddamn vaginocracy, with both senators and its governor being women. Awesome!
