Certainly our assumption, based on the evidence from other countries and from the research, is that having it on Sunday does increase turnout, as some studies say, by 10%. Anecdotally, if you connect the complaint people have, the general 35% to 40% of those who didn't vote who say the reason they didn't vote was that they were too busy with work or school or other types of commitments—those commitments, for many, do not exist on a Sunday, so that increases that possibility. And that is the principal objective here, to encourage voter participation, as the name of the bill implies.
