If the Democratic field of candidates for president were a weather phenomenon, you could call it Hurricane Occupy.

Pushed by Bernie Sanders, the passionate left-leaning Senator from Vermont, Hillary Clinton and Martin O'Malley have used some of their early speeches and policy proposals to establish street cred on arcane, specific reforms of the financial system: high-frequency trading, dismantling major banks, corporate earnings announcements.

The proposals aim to curb the power of big businesses and big banks that populate Wall Street. They're trying to outdo each other, but as the policies become more and more specific, it's less likely that there will be a wide pool of Americans who will be galvanized to go to the polls.

Last Thursday, Former Maryland governor Martin O’Malley laid out a series of reforms that included a three-year revolving door ban to prevent Wall Street bankers from retiring in Washington. Sanders, meanwhile, has largely led the pack in his anti-Wall Street rhetoric, throwing shots at the stock market since he entered the race. Sanders, who calls himself a socialist, introduced legislation in May that would break up the too-big-to-fail banks.

On Friday, frontrunner Hillary Clinton gave a speech on how she’d shift corporate culture to value long-term investments over short-term earnings.

Clinton said last week that her plans to “reign in excessive growth on Wall Street” would come in the next few days.

“There’s sort of a populist current running through the Democratic party,” Christopher Arterton, a professor at George Washington University, told Mashable. “That means they want to focus on business interests, particularly the super rich that they find in Wall Street and hedge funds.”

A petition from progressive political action committees Progressive Change Campaign Committee, Democracy for America, and Rootstrikers, which asks candidates to “to stop the revolving door between Wall Street and Washington by appointing fewer Wall Street insiders to top government economic positions” has already garnered over 63,000 signatures.

“The fact that all the major Democratic candidates have come out early on, suggests that they’re hearing that voters are deeply concerned with Wall Street’s stranglehold and want to put forward ways to address it,” Neil Sroka, the communications director for Democracy for America, told Mashable.

The proposals are peppered with lingo that’s all too familiar to Wall Street bankers and those in the c-suite. Clinton says she’d increase capital gains taxes on the nation’s highest earners, while O’Malley says he’ll bring back the 1933 Glass-Steagall Act, which placed strict limits on the nation’s biggest banks.

And indeed, O’Malley has championed himself as the man who will take down Wall Street to save the middle class. In an open letter to the Wall Street megabanks, which was obtained by Business Insider, O’Malley proclaimed: “As President, I have no plans to let up on you.”

“If you—and your megabanks—which we, the American taxpayer, saved want to begin to restore the confidence in your leadership, you need to start by saying two things: "we’re sorry" and "thank you,’” O’Malley wrote.

Clinton has taken a more balanced approach, positioning herself as an Clinton positioned an advocate for all Americans who work hard — from the middle class to business leaders — but noted that the system is unfavorably tilted to benefit the rich.

“Now I am all for rewarding CEOs well when their companies prosper and their employees also share in the rewards,” Clinton, who also advocated for increasing the minimum wage, said on Friday. “But there is something wrong when senior executives get rich while companies stutter and employees struggle….What’s good for middle class families also happens to be good economics.”

“The policies that Mrs. Clinton has signed onto for the moment are rather mild,” Arteron said. “And perhaps many of the Wall Street people breathed a sigh of relief.”

And that mildness might come from the support Clinton receives from Wall Street and Silicon Valley, according to Arterton. And some on Wall Street, according to a report from Politico, are also concerned that Clinton might swing too far to the left, thanks to pressure from Sanders and O'Malley.

Clinton receives the most funding from the execs of the big banks out of all candidates so far in the race, and two of her closest aides in the State Department have stints at the big banks on their resumes.

Tom Nides, the deputy secretary of state for management and resources from 2011-2013, was an executive at Morgan Stanley, while Robert Hormats, the former under secretary of state for economic growth, energy and the environment, is a former vice-chairman at Goldman Sachs.

“It’s really hard to imagine how a presidential candidate is going to seriously confront the powerful, greed-driven interests on Wall Street when they’re getting advice whispered in their ear from people who just walked out of the banks responsible for the crash of the economy in 2008,” Sroka said, adding that Clinton has yet to follow Sanders and O’Malley’s lead in criticizing the revolving door between Wall Street and Washington.

And her rivals have taken notice of Wall Street ties as well. “Her closeness with big banks on Wall Street is sincere...and well known. I don’t have those ties,” O’Malley said in an interview with WKXL in New Hampshire on Sunday.

But ultimately it will be up to Democratic voters to decide which Wall Street policies they like better — or whether they even care about the Dodd-Frank Act and revolving doors — come primary time.
