Sam Heldman is worried about a filibuster over Pickering but Dwight Meredith and Atrios argue that "mojo" as is a muscle that strengthens with use.
That may be true for us but not for the Senate. Don't look to the them for support, force them to follow. If the pressure builds, we won't need a filibuster. Not to sound melodramatic but it's up to us, or at least to Atrios and Josh Marshall.
