One day before Supreme Court nominee Elena Kagan is set to appear before the Senate Judiciary Committee, the committee's top Republican upped his critiques of the nomination and floated the possibility of a filibuster. Appearing on CBS's "Face the Nation," Sen. Jeff Sessions (R-Ala.) said it was "conceivable" that a "filibuster might occur," should Kagan prove during the hearings to have extraordinary views. Even if a filibuster doesn't materialize, however, the hearings won't be short of political dramatics.
