As much as Republicans used to be pro-business, Democrats historically have believed in strong government oversight of private businesses. I think the poll reflects a mix of traditional Democrat/Republican values for some, and how those values have evolved for others.
Similarly, private businesses used to be among the most conservative organizations within the United States, headed by a bunch of middle-aged white guys with "traditional" values. (Try to imagine where Walt Disney would have stood on this.) Not anymore.
Things change.
