The Politico reports on the Supreme Court’s decision to hear reargument in Citizens United and other campaign finance developments.

Both the public financing and FEC debates, however, are overshadowed by a pending development over which Obama has no control: the Supreme Court’s surprise announcement last week that, in lieu of deciding a relatively narrow case about whether restrictions on corporation-funded broadcast ads also applied to movies, it would consider overturning the restrictions as a whole. 

Those restrictions are a major pillar of McCain-Feingold. And the court’s announcement that it would hear arguments in September from the Obama administration and the group challenging the restrictions prompted angst among the reformers, who predicted a sweeping decision could reverse the century-old prohibition on corporate contributions to candidates.
