  We present a new method for measuring the CMB temperature quadrupole, using
large scale CMB polarization. The method exploits the fact that CMB
polarization is partially sourced by the local temperature quadrupole. We link
the temperature with the polarization spectrum directly by relating the local
quadrupole at the onset of reionization to both of them. The dominant
contribution is at l<30 and since we use many l values, we can reduce the error
significantly below cosmic variance. In particular, for our fiducial model, the
error on the temperature quadrupole is reduced to 24%. This has the potential
of reducing the probability of a low quadrupole by two orders of magnitude.
