Proposition 19, the measure on the November ballot to legalize and tax marijuana, raised a total of $370,565.64 through the end of June, a relatively paltry portion of which came from donors in San Diego County. Danny Craig, a teacher with the Grossmont Union High School District, gave $100, according to disclosure records filed with the state. El Cajon attorney Eric Isaacson of the firm Robbins Geller Rudman & Dowd gave $125. Last year he got an award from the Unitarian Universalist Association for his volunteer work on behalf of gay marriage. Margaret Ketner of San Diego, a botanist/software engineer with United International Disjunct, Inc., gave $159.
