For quite a few years, Warren was a registered Republican in Pennsylvania and Massachusetts. It wasn't until she was 47 years old and a Harvard professor that she suddenly changed parties.
Warren has acknowledged her Republican past before, but she does not often discuss it, or else downplays it. In a recent interview over tea at her home in Cambridge, Massachusetts, she said she assumes the first time she registered as a Democrat was 1996, but added, “I’m not even 100 percent sure what I was registered as.” According to Warren, in the six presidential elections she voted in before 1996, she cast her ballot for just one GOP nominee, Gerald Ford in 1976. She does not talk about her Republican past in either of her books or as part of the biography she recounts in her stump speech; the information often comes as a surprise even to Beltway politicos and longtime Warren allies.More
