When U -> 0, the electrons form a glass with Anderson localized states. At half filling, a regular array of charges (Mott insulator) is pinned by the random substrate when U -> \infty. Between those two insulating limits, we show that there is an intermediate regime where the electron glass becomes more liquid before crystallizing. The liquid-like behavior of the density-density correlation function is accompanied by an enhancement of the persistent current.5 pages, Latex, uses moriond.sty (included), Contribution to the Proceedings of the Rencontres de Moriond 1999Strongly Correlated ElectronsDisordered Systems and Neural NetworksMesoscale and Nanoscale Physicstext
