In addition to this immediate drowning out of noncorporate voices, there may be deleterious effects that follow soon thereafter. Corporate ‘domination’ of electioneering can generate the impression that corporations dominate our democracy. When citizens turn on their televisions and radios before an election and hear only corporate electioneering, they may lose faith in their capacity, as citizens, to influence public policy. A Government captured by corporate interests, they may come to believe, will be neither responsive to their needs nor willing to give their views a fair hearing. The predictable result is cynicism and disenchantment: an increased perception that large spenders ‘call the tune’ and a reduced ‘willingness of voters to take part in democratic governance.’ To the extent that corporations are allowed to exert undue influence in electoral races, the speech of the eventual winners of those races may also be chilled.
Politicians who fear that a certain corporation can make or break their reelection chances may be cowed into silence about that corporation.
On a variety of levels, unregulated corporate electioneering might diminish the ability of citizens to ‘hold officials accountable to the people,’ and disserve the goal of a public debate that is ‘uninhibited, robust, and wide-open.’

After all, a district judge who gives harsh sentences to Yankees fans and lenient sentences to Red Sox fans would not be acting reasonably even if her procedural rulings were impeccable.

All general business corporation statues appear to date from well after 1800.. The Framers thus took it as a given that corporations could be comprehensively regulated in the service of the public welfare. Unlike our colleagues, they had little trouble distinguishing corporations from human beings, and when they constitutionalized the right to free speech in the First Amendment, it was the free speech of individual Americans they had in mind.
The fact that corporations are different from human beings might seem to need no elaboration, except that the majority opinion almost completely elides it…. Unlike natural persons, corporations have ‘limited liability’ for their owners and managers, ‘perpetual life,’ separation of ownership and control, ‘and favorable treatment of the accumulation of assets….’ Unlike voters in U.S. elections, corporations may be foreign controlled.
...It might be added that corporations have no consciences, no beliefs, no feelings, no thoughts, no desires. Corporations help structure and facilitate the activities of human beings, to be sure, and their ‘personhood’ often serves as a useful legal fiction. But they are not themselves members of ‘We the People’ by whom and for whom our Constitution was established.
