An Early Halloween Fright for Wall St.: Elizabeth Warren for Treasury Secretary?

"I don't think so," she tells PEOPLE in an interview conducted at Warren's Cambridge, Massachusetts, home for this week's issue. "If there's any lesson I've learned in the last five years, it's don't be so sure about what lies ahead. There are amazing doors that could open."
She just doesn't see the door of 1600 Pennsylvania Avenue being one of them. Not yet, anyway. "Right now," Warren says, "I'm focused on figuring out what else I can do from this spot" in the U.S. Senate.
The former Harvard Law School professor whose aggressive oversight of the financial industry after the 2008 economic meltdown not only won her a national reputation as watchdog for average Americans and swept her into national office in 2012, but turned her into an Internet sensation.
But when she reviews the clips herself, Warren second-guesses whether she's being tough enough. "I watch and think, 'Damn! I should have gotten that question a little sharper,' " she admits with a laugh.
But all that makes for click-bait on YouTube also makes her a lightning rod on Wall Street.
"They're scared to death of Elizabeth Warren because she knows not only how banks operate, but she knows all about anti-trust law," says Tufts University political science professor Jeffrey Berry.
So, if not chief executive, how would Warren feel about being Treasury Secretary under a President Hillary Clinton? Warren belts out a big, Clinton-caliber belly laugh. "Well, THAT'S a fun thought!"
As for Clinton, Warren says of the two women's relationship: "We have talked. It's not much more than that. Not much more."
