Ned Foley has posted this article (George Washington Law Review) on SSRN. Here is the abstract:

This piece examines the first major test of provisional voting after the enactment of the Help American Vote Act of 2002 (HAVA). The 2004 presidential election demonstrated the HAVA system of provisional voting is seriously underdeveloped, in large part because of ambiguities and gaps in HAVA itself. These deficiencies prevent provisional voting from serving as the “insurance policy” HAVA intended it to be. The article recommends that, before the 2008 presidential election, new legislation should be enacted that would establish preelection mechanisms for verifying voter eligibility and that these preelection verification procedures be used to streamline postelection disputes over provisional ballots.
