Favoritism and influence are not . . . avoidable in representative politics. It is in the nature of an elected representative to favor certain policies, and, by necessary corollary, to favor the voters and contributors who support those policies.Lessig rightly argues that Kennedy was just plain wrong to imply that the framers intended representatives in Congress to represent the interests of anyone other than voters, including campaign contributors.
As a practical matter, I don't believe Citizens United changes much. There were always other avenues by which corporate money could influence electoral contests. As a matter of constitutional law, however, I think it both a bad ruling and an unwise one.
