Marin County, CA turnout increase due to VBM?

A surprisingly balanced editorial in the Marin, CA Independent Journal lauds a vote by mail for encouraging turnout in a local school bond election.  Turnout was 56%, 11% higher than the last local election held in 2009.

However, the rest of the story notes that Marin has one of the highest turnout rates in most elections, and that the campaign for this election was very well-financed, including multiple calls to registered voters encouraging them to return the by-mail ballot. ¬† The editorial ends by once again attributing all the turnout increase to the administrative change (including a completely invalid comparison to turnout in LA County), nonetheless, overall it’s a pretty nuanced account.
