As Daniel Patrick Moynihan once put it, you are entitled to your own opinions, but not your own facts. Spend a few minutes reading about polling methodologies and playing around with a sample size calculator. California's number of registered voters was around 18.25 million in 2012. Put in 19 million if you're feeling generous to your own opinions.
Also, all 50 states allow minors to wed with parental consent. http://en.wikipedia.org/wiki/Age_of_marriage_in_United_State...
Thus the campaign for "marriage equality" has
a narrow definition of equality and should be
renamed the campaign for "same-sex marriage".
