A number of Pew-sponsored studies of non-precinct place voting were released recently, and they are available here. Here is a quick description:
In 2008, Make Voting Work (MVW), a project of the Pew Center on the States funded through The Pew Charitable Trusts and the former JEHT Foundation, released a Request for Proposals (RFP) for research that would examine alternatives to precinct-based election day voting, including early in-person and absentee voting and vote by mail systems. MVW issued this RFP to advance research in this area and as a complement to the broader Pew Center on the States research agenda.
Seven projects were selected that cover many of the unseen effects of non-precinct place voting methods as well as some of administrative and procedural hurdles that election officials face in conducting these programs. The final reports, and the data where available, are posted below.
