The Effect of Electronic Voting Machines on Change in Support for Bush in the 2004 Florida Elections by Michael Hout, Laura Mangels, Jennifer Carlson, and Rachel Best.

This working paper just came out today (11/18/04). There are some pretty strange findings and the authors say they are “99.9% sure that these effects are not attributable to
chance.” Makes one wonder.

Electronic voting raised President BushÕs advantage from the tiny edge he held in 2000 to a clearer margin of victory in 2004. The impact of
e-voting was not uniform, however. Its impact was proportional to the Democratic support in the county, i.e., it was especially large in Broward, Palm Beach, and Miami-Dade.
