Proposition D SAN FRANCISCO, CA (kalw) - San Franciscans will be asked to approve or reject Proposition D, a ballot measure essential to the future of San Francisco's libraries, according to its supporters. Passage of Prop D would renew a fund set to expire soon... But critics of Prop D say that it's not a renewal it's a deceptive revision and it will actually drain money from the libraries' core mission of providing books and other services. © Copyright 2009, kalw
