As I noted, I cannot with confidence make predictions about the outcome of the Citizens United case based on oral argument questions, given the recent experience in NAMUDNO in which CJ Roberts and Justice Kennedy seemed sure votes to overturn section 5 of the Voting Rights Act but did not. But there was absolutely nothing in the Citizens United oral argument questions of the two likely "swing justices" in this case to give any comfort to those who believe that Congress should have the power to limit corporate spending in candidate elections.
Rick is one of the top election law scholars in the country, and is generally a supporter of restrictions on corporate speech about candidates, so he isn't just hearing what he hopes to hear. Rick also reports that "Justice Sotomayor asked the questions I would have asked" -- high praise from any law professor! -- "and seems likely to be a very strong replacement for Justice Souter on campaign finance issue."
