It's all the more intriguing given the likelihood that Justice O'Connor won't be sitting in the case.

Justice O'Connor has been the key vote in everything from campaign finance to the meaning of the Voting Rights Act to racial gerrymandering to Bush v. Gore.

Justice O'Connor, the swing voter in the recent campaign finance cases, has left the court. The Vermont case could present the new Roberts Court with an opportunity to begin imposing significant restrictions on the ability of the government to limit the role of money in politics.

I think we're likely to enter into an era where the court is more skeptical and will strike down campaign finance rules.

This could be an important first step toward undermining (the 2003 ruling) without overruling it.
