A Defense Of Occasional Voters

 Sendhil Mullainathan mounts one. He discovered that voting increases polarization, that it “effectively committed people to a candidate or party”:

A combination of neutrality and persistent voting would be ideal. But our psychologies are complicated. If they override our narrow self-interest and lead us to vote instead of free-riding, the very act of voting may make us more partisan. Sporadic voters can provide an antidote: Their previous lack of engagement may serve as a counter to partisanship.

There is a line between apathy and neutrality. People who sit out all elections provide little value to a democracy. People who sit out some elections, jumping in at crucial times, serve an important role as a reserve army of the uncommitted.
