  In the absence of disorder, electrons can display glassy behavior through
supercooling the liquid state, avoiding the solidification into a charge
ordered state. Such supercooled electron liquids are experimentally found in
organic $\theta$-$MM'$ compounds. We present theoretical results that
qualitatively capture the experimental findings. At intermediate temperatures,
the conducting state crosses over into a weakly insulating pseudogap phase. The
stripe order phase transition is first order, so that the liquid phase is
metastable below $T_s$. In the supercooled liquid phase the resistivity
increases further and the density of states at the Fermi level is suppressed,
indicating kinetic arrest and the formation of a glassy state. Our results are
obtained using classical Extended Dynamical Mean Field Theory.
