Until Kevin Cramer entered the Senate, the last time the GOP held all four Senate seats in the Dakotas was in....1960.
Despite being such a liberal state, New Jersey has never had a woman in the senate. Same with Connecticut.
Vermont is one of the most liberal states in the county. It’s also the only to have never sent a woman to congress.
https://en.wikipedia.org/wiki/Women_in_the_United_States_SenateDon't forget that there are a handful of other blue states that have never elected or sent any women to the Senate. As for New Jersey, they've also sent very few women to Congress. On the other hand, they had one woman who served as governor.
I'm amazed that New Jersey has never had a Jewish governor despite being close to New York and being a liberal state with a large Jewish population. I wouldn't be surprised if Nevada and Arizona ended up achieving that milestone before New Jersey.
As for Vermont, they haven't sent any women to Congress because their representatives stay in office for a long time and they only have one House seat. They did have one woman serve as governor though.
