This week: New polling shows some, but not substantive, shifts in the races for California governor and U.S. Senate. We also discuss the event featuring the Senate candidates (was it really a debate?). And we look at the major 2020 fight over the legacy of Prop 13 and The Times' final installment of the series "The Next California." With John Myers, Melanie Mason and Liam Dillon of the Los Angeles Times.
