First of all, there's the evidence over the last two general elections, in 2011 and 2015. For those elections we had advance polls, in one case on an Easter weekend and in the latest example on a Thanksgiving weekend. On both occasions we saw a record turnout for advance polls, and significant increases.
For the first time, we also had voting at advance polls on a Sunday in the last election, and roughly 25% of the turnout was due to that Sunday voting.
Again it's early evidence, but there is evidence that electors appreciate the convenience of being able to vote on a weekend or even on a statutory holiday. That's for sure.
Whether there is.... I'm sorry. I lost part of your question.
