If it takes an imagined presidential run to generate interest in her signature issue of banking reform, freshman Senator Elizabeth Warren won’t be issuing any Shermanesque statements. A professor turned politician, she was among the first to sound the alarm bell on a runaway banking industry, and now she’s using her seat on the Senate Banking committee to warn of another “too big to fail” crisis in the making. Praised for her tenacity in penetrating the obscurity created by Wall Street to shield high-risk derivatives from scrutiny, and her clarity in exposing these practices to the American people, Warren would be a dream candidate for those who cheered last year’s Occupy Wall Street movement, and for progressives in general.
