Washington (CNN) - They do well with Wall Street, but Democrats may now risk biting the hand that feeds many of them as President Obama and top party leaders press for financial reform.

"Can we predict the future? Of course not. If legislation is passed that is particularly onerous to this industry [that] might change its tune," said Dave Levinthal with the nonpartisan Center for Responsive Politics and OpenSecrets.org. "That's entirely possible, but there's no indication of that yet."
