The WaPo reports, Drilling opponents will try first to strip the ANWR provision by asserting that it flouts Senate rules against unrelated legislation on spending bills.
If that fails, members from both parties are raising the politically risky prospect of a filibuster that would take 60 votes to break.
Both Kerry and Cantwell have vowed to filibuster. Stevens, the former Appropriations Committee chairman who sponsored the ANWR drilling provision is "a master of legislative larding, but this latest gambit may be riskier than usual." We can best remember Stevens earlier this year for his "Bridge to Nowhere."
