This isn't a huge difference, but it's certainly worth noting. The spread in favor of regulation is 14 points when you mention "Wall Street" banks but only 3 points when you don't. Republicans, of course, are well aware of this already, which is why they've chosen to endlessly repeat "Wall Street bailout" as their preferred lie about what the Senate financial reform bill does. Surely the good guys should be doing the same?
(Not lying, that is. The "Wall Street" thing.)
