The Judiciary Committee's weird obsession with Citizens United

Why the obsession with the Citizens United campaign finance case? Almost every senator from both sides of the aisle has invoked the case: Democrats to bemoan the "conservative activism" of the Roberts court and its alleged bias toward corporate bigwigs; Republicans to defend the court's conservatives and to poke the president for using the State of the Union to criticize the decision. Solicitor General Elena Kagan, who defended the law against constitutional challenge, has been asked repeatedly about her position in the case. The question has been asked and answered -- ad nauseum. Democrats need to stop their pontificating, which seems based on the assumption that if they yell loud enough Kagan will get the message that she should, if confirmed, vote to uphold campaign law in the future. Republicans need to remember that Kagan was only doing her job as solicitor general in defending a law that they -- the Congress -- passed. Enough already.
