 However, there is a general challenge to these arguments in support of a duty to vote. Call this the particularity problem: To show that there is a duty to vote, it is not enough to appeal to some goal G that citizens plausibly have a duty to support, and then to argue that voting is one way they can support or help achieve G. Instead, proponents of a duty to vote need to show specifically that voting is the only way, or the required way, to support G (J. Brennan 2011a). The worry is that the three arguments above might only show that voting is one way among many to discharge the duty in question. Indeed, it might not be even be an especially good way, let alone the only or obligatory way to discharge the duty.
