I wonder if anyone's done a breakdown by size of business. National Republicans (since we're talking about presidential administrations), while they talk a lot about small business, really pay attention to big business when formulating policy. More local Republicans may be friendlier to small business, and get better results for them. (I actually think that's the main source of the "pro-business" reputation.)
But more broadly, I think it's entirely possible for smart businesspeople to support policies that they believe will be profitable for their own company, and not realize that they have negative consequences for the broader economy that will overwhelm the personal benefit. It's very easy to classify those effects as things that "just happen" and not see any connection with policies whose obvious direct effects are positive for you.
