I have two concerns about this initiative (haven't voted yet and am not sure how I will):
1. What are the consequences of ignoring it?
Referenda on citizen initiatives count as federal elections. Failure to vote in three consecutive federal elections results in deregistration. If you have no opinion on the referendum question but wish to avoid missing the election, you may vote "Abstain" and you will be considered, for Census Bureau purposes, to have voted in the election.
And, of course, if you do ever realize that you have missed three consecutive federal elections, you may re-register without delay or penalty.
