Leftist.
Scalia:
People who associate who pool their financial resources for pur- poses of economic enterprise overwhelmingly do so in the corporate form; and with increasing frequency, incorpora- tion is chosen by those who associate to defend and promote particular ideas such as the American Civil Liber ties Union and the National Rifle Association, parties to these cases. Imagine, then, a government that wished to suppress nuclear power or oil and gas exploration, or automobile manufacturing, or gun ownership, or civil liberties and that had the power to prohibit corporate advertising against its proposals. To be sure, the individuals involved in, or benefited by, those industries, or interested in those causes, could (given enough time) form political action committees or other associations to make their case. But the organizational form in which those enterprises already exist, and in which they can most quickly and most effectively get their message across, is the corporate form. The First Amendment does not in my view permit the restriction of that political speech. And the same holds true for corporate electoral speech: A candidate should not be insulated from the most effective speech that the major participants in the economy and major incorporated interest groups can generate.
