"Advocates of campaign finance restrictions, outraged by the Citizens United decision, have proposed a constitutional amendment allowing Congress and the states to regulate political speech 'by any corporate entity.' The breadth of this proposal is, well, breathtaking: it would permit the criminalization of political advocacy (including criticism of political candidates) not just by presumptively big bad corporations, but by non-profit advocacy groups, large and small; and, its intended effect on media corporations is unclear."
