The video just above is one of the best congressional campaign clips I've seen from anyone anywhere. Please watch it. June 7 is going to be another SuperTuesday, a congressional one. California, Iowa and New Jersey have red hot primaries pitting grassroots progressives like Lou Vince, Pat Murphy and Alex Law against establishment hacks like, respectively, Brian Caforio, Monica Vernon and Donald Norcross. South Dakota, New Mexico and Montana have primaries the same day but without the fiery contests.And Law's isn't the only congressional contest that needs to be watched in New Jersey.
