A recount is required if the difference between Yes and No votes is not more than one-fifth of one percent of the total votes cast (which in this case, would be 3,012 votes).
In the case of Measure 92, certified “No” votes outnumbered “Yes” votes by just 812 out of 1,506,144 votes cast, so fall within that margin.
The final tally (click HERE) was 752,666 votes in favor (49.9730437% ) vs 753,478 against (50.0269563%).
A similar GMO labeling proposal in Colorado was defeated fairly soundly (65.47% against vs 34.53% in favor - click HERE).
However, an initiative to place a moratorium on the cultivation of GMOs in Maui County in the Hawaiian islands (where Monsanto and Dow operate seed nurseries) passed, albeit very narrowly (51% in favor; 49% against - click HERE) and is now subject to a legal challenge.
To date, three states - Maine, Connecticut and Vermont - have passed GMO labeling laws, but those in Maine and Connecticut are contingent upon other states following the same path, while Act 120 in Vermont, which will take effect in 2016, is also being challenged in the courts.
GMO labeling proposal in California (Prop 37) and Washington State (I-522) were both narrowly defeated in 2012 and 2013 respectively.
