My point is directed at those who claim that no tax exempt, or no corporations period, should be allowed to engage in political activity
My example is a corp formed only to pool money of like minded people who are contributing soley to support a specific political policy.
You seem to be speaking of a 'regular' (for profit) corporation, a publicly held company, e.g., Apple Inc. When that SCOTUS ruling was announced I felt that those types of corporations were not going to engaged in general campaign politics, like supporting either Obama or McCain, because their shareholders, some of whom support Obama and others McCain, would object. I don't know how that has worked out but the last study I saw suggested they weren't contributing. (But if they were and I was a shareholder I'd be hella pissed off no matter which candidate they supported.)
Now privately or closely held corps is another matter. Some of those can be damned big, and if a single person or a family owns them I expect they could agree whom to support and would do so. (Note that such expenditures would NOT be deductible for income tax purposes.)
Some publicly held for-profit corporations certainly have legitimate business interests in influencing policy and I would expect them to pursue it. However, this is usually in the form of lobbying and that has nothing to do with the SCOTUS case. E.g., an oil company lobbying to open up federal lands for exploration; I don't see why a shareholder (or employee) would object to that. (Note that expenditures for lobbying are NOT deductible either.)
