This is one of the better election hacking stories and possibilities I've read about. Most people are (understandably) fixated on hacking that would tamper with the actual voting results. But I remember the poll book software and laptops (which we use to check whether someone is a registered voter, and their current voting status, before giving them a ballot) being a conspicuous and clunky black box. Not egregiously moreso than any proprietary Windows app, but someone compromising the app or the voter data (which in Cook County, IIRC, is done via on-air wifi updates) would theoretically be hard to detect. In swing districts, making it harder for 10% of one party's voter roll to cast votes would have significant impact.
