  We present the most recent lattice results for the lowest-order hadronic
contribution to the muon anomalous magnetic moment using 2+1 flavor improved
staggered fermions. A precise fit to the low-q^2 region of the vacuum
polarization is necessary to accurately extract the muon g-2. To obtain this
fit, we use staggered chiral perturbation theory with the inclusion of the
vector particles as resonances, to evaluate the vacuum polarization. We discuss
the preliminary fit results and attendant systematic uncertainties, paying
particular attention to the relative contributions of the pions and vector
mesons.
