  We develop the dual description of $2+1$ SU(2) lattice gauge theory as
interacting `abelian like' electric loops by using Schwinger bosons. "Point
splitting" of the lattice enables us to construct explicit Hilbert space for
the gauge invariant theory which in turn makes dynamics more transparent. Using
path integral representation in phase space, the interacting closed loop
dynamics is analyzed in the weak coupling limit to get the mass gap.
