Democratic Sen. Elizabeth Warren was a registered Republican, but she said she changed her political affiliation once she saw an eroding middle class under her (now former) party.
In the late mid 1990s, Warren said she was watching what was happening to America's working families and noticed they were in debt.
"I looked around the middle of that fight and I realized all the money was on one side and all the hurting was on the other and that's when I jumped in politically. I got in that fight and I fought it for 10 years, and by the end of that fight I fully understood that every single Republican stood there for the banks and half of the Democrats did. So my party was the party that at least we got half of them to stand up for working people, and that was the big change for me," she said.
