A thornier problem, which seems to be overlooked: can a corporation really choose its point of view, or is its point of view dictated to it by laws and obligations? What happens if a corporation endorses a candidate who enacts policies which decrease shareholder value? Ultimately, I think we'll end up with a body of case law which eliminates any idea of "freedom" from the process and either forbids corporations from endorsing candidates (since it's too risky trying to predict the result) or forcing them to endorse only candidates who adopt specific positions.
