- Fighting back against “Citizens United:” Senate Democrats, led by Tom Udall, have introduced a constitutional amendment meant to blunt the effects of Citizen’s United, the Supreme Court decision that paved the way for unlimited, undisclosed campaign contributions by corporations. The amendment wouldn’t directly overturn CU, but rather give congresses–both federal and state–the authority to regulate campaign contributions and expenditures. Like most proposed constitutional amendments, it probably won’t get anywhere close to ratification, but hey, it rallies the base, right? source
