It turns out that Elizabeth Warren, the Massachusetts Senate candidate who has a special knack for agitating Republicans, used to be one of them.

“I was a Republican, because I thought that those were the people who best supported markets. I think that is not true anymore,” said Elizabeth Warren in an interview with The Daily Beast.

Warren, who has made Bay State and national Democrats swoon since she entered the race to challenge Republican Scott Brown in 2012, was 46 when she made the conscious decision to dabble in Democratic politics, according to the interview.  The interview also said that she first resisted the urge to get involved with politics but then changed her mind after serving on a panel that was tasked with recommending  reforms to the bankruptcy laws.

“I can’t just leave this to people who are going to wreck the lives of millions of American families if they get the chance,” said Warren as part of the Daily Beast interview.

Warren first  gained national notoriety for grilling Treasury Secretary Timothy Geither while serving on the congressional TARP oversight panel in 2009 and gained further notoriety among Republicans for helping to create the Consumer Financial Protection Bureau.

She recently agitated Republicans for suggesting that businesses have a responsibility for paying it forward to future generations.

Other famous party switchers include Republican President Reagan, Secretary of State Hillary Clinton and former Secretary of State Condoleezza Rice.
