Abstract
In November of 2007, Illinois became the only state to require that voters casting optical scan ballots be alerted to undervotes via the emission of an audible beep and ballot “kickback” when they insert their ballot into the optical scanning machine. The 2010 Illinois General Primary was the first election for which the undervote alert was to be implemented. Yet, of 99 counties employing optical scanning technology, 12 did not upgrade their machines in time for the election, citing a shortage of time to do so. The uneven implementation of the Illinois undervote alert presents a unique opportunity to examine whether such an external stimulus is an effective deterrent of aggregate undervoting, within the context of a precinct-level panel study. I find little evidence that the audible alert affected undervote patterns in the 2010 General Primary election.
