We reconsider the electrostatic contribution to the persistence length, $\ell_{\rm e}$, of a single, infinitely long-charged polymer in the presence of screening. A Gaussian variational method is employed, taking $\ell_{\rm e}$ as the only variational parameter. For weakly charged and flexible chains, crumpling occurs at small length scales because conformational fluctuations overcome electrostatic repulsion. The electrostatic persistence length depends on the square of the screening length, $\ell_{\rm e}\sim\kappa^{-2}$, as first argued by Khokhlov and Khachaturian by applying the Odijk-Skolnick-Fixman (OSF) theory to a string of crumpled blobs. We compare our approach to previous theoretical works (including variational formulations) and ...
