1. Campaign Finance Reform

Kagan has already distinguished herself as an aggressive advocate for campaign finance reform. The first case Kagan argued as solicitor general was Citizens United v. Federal Elections Committee, arguably the most important case in recent judicial history and ground zero for political speech. It was one of the many cases Obama referenced when he said back in April, "In a democracy, powerful interests must not be allowed to drown out the voices of ordinary citizens." In one fell swoop, the Court upended decades of campaign finance laws that kept corporations and their unlimited financial resources out of the political process. Kagan argued that if Roberts and the other conservative justices had their way, which they ultimately did, the voice of the ordinary American would simply be overpowered by the deep pockets of corporate America. This issue is not going away anytime soon. In one way or another, it will be before the Court in the coming years and the next justice will play a critical role in the outcome.
