Can Hillary Clinton Win the Democratic Race for Toughest Wall Street Cop?

The first Democratic presidential debate Tuesday in Las Vegas is primed to make Wall Street very uneasy, with candidates expected to jockey over who can be the toughest sheriff on financial institutions to keep pace with the populist undercurrent sweeping the party and shaking up the race for the nomination.

As she prepared to leave the campaign trail for a few days of debate prep, front-runner Hillary Clinton teed up a plan to crack down on Wall Street. Meanwhile, two of her rivals for the Democratic presidential nomination, Senator Bernie Sanders of Vermont and former Maryland Governor Martin O'Malley, already have been touting more far-reaching proposals to break up the biggest banks and reinstate the Glass-Steagall law that imposed separation between commercial and investment banking.
