The Judicial Crisis Network slams Landrieu in the ad for voting "for every one of Obama's liberal activist judges."


It also charges that, in voting to eliminate the filibuster for certain judicial nominees, she "helped change to rules to pack a key court with new liberal judges who will review … agencies Obama is using to push his unconstitutional job-killing agenda."
