San Diego Union Tribune slams Proposition 4 critics, citing popular support among California voters in a September 23, 2008 editorial.

Questioning the oppositions' "adamant objection to requiring parental notification or family notification in the few cases of parental abuse", the editorial begs: "Under what other circumstance would these critics contend that the suspected abuse of a child by her parents should not be reported to authorities?"

Opponents to Proposition 4, "misread the public" states the Union Tribune, noting that most Americans want abortion to be "safe, legal and rare". Teen abortion rates, teen pregnancy rates and rates of teen sexually transmitted infections have significantly declined in the 34 states that have enacted parental involvement or notification laws.

Endorsing the initiative due to notification of adult family members in lieu of parents in certain circumstances, the San Diego Union Tribune says: "This time, it is a significantly improved proposition" and "It should pass."
