Faced with profound political and econom- ic transition, organizers have begun exper- imenting with a new form of movement infrastructure called strategic power-building alignments (alignments). These alignments are sustained, collabora- tive alliances between strong power-build- ing organizations that share a long-term aim of shifting the state-level policy terrain to advance a transformative agenda. These alignments are an important element of the infrastructure needed to advance alterna- tive economic paradigms.
