  We report on a Rosenbluth separation using previously published data by the
CLAS collaboration in Hall B, Jefferson Lab for exclusive $\pi^{0}$ deeply
virtual electroproduction (DVEP) from the proton at a mean $Q^{2}$ of $\approx$
2 (GeV/c)$^{2}$. The central question we address is the applicability of
factorization in $\pi^0$ DVEP at these kinematics. The results of our
Rosenbluth separation clearly demonstrate the dominance of the longitudinal
contribution to the cross section. The extracted longitudinal and transverse
contributions are in agreement with previous data from Hall A at Jefferson Lab,
but over a much wider $-t$ range (0.12 - 1.8 (GeV/c)$^{2}$). The measured
dominance of the longitudinal contribution at $Q^{2} \approx$ 2 (GeV/c)$^{2}$
is consistent with the expectation of the handbag factorization theorem. We
find that $\sigma_L(t) \sim 1/(-t)$ for $-t >$ 0.5 (GeV/c)$^2$. Determination
of both longitudinal and transverse contributions to the deeply virtual
$\pi^{0}$ electroproduction cross section allows extraction of additional GPDs.
