Feinstein, 89, has been in the public eye for more than a half-century, notably since she became San Francisco’s leader after the 1978 assassinations of Mayor George Moscone and Supervisor Harvey Milk. In recent years, she has faced mounting questions about her mental acuity and her old-school brand of bipartisanship that is viewed as outdated in today’s bitterly divided era. These factors led Democrats to leap into the race to replace her before she announced her intentions — a move that would previously have been considered impolitic.

Rep. Katie Porter, 49, Democrat

Resume:
The Iowa native is an attorney and a protégé of Sen. Elizabeth Warren, whom Porter met while taking Warren’s bankruptcy law class at Harvard Law School. In 2011, Porter moved to California when she became a law professor at UC Irvine. The following year, then-California Atty. Gen. Kamala Harris appointed Porter to be the state’s independent monitor overseeing the state’s share of a $25-billion mortgage settlement with banks.

Rep. Adam B. Schiff, 62, Democrat

Resume:
Schiff was born in Massachusetts and moved with his family to Arizona and then California. He was the valedictorian of his 1978 graduating class at Monte Vista High School in Danville high school, where his classmates voted him most likely to succeed. After attending Stanford University and Harvard Law School, Schiff became a federal prosecutor. Among his most prominent cases was prosecuting an FBI agent who became a Russian spy.

Rep. Barbara Lee, 76, Democrat

Resume:
Lee has a deep history of political activism, dating back to when she was a college student at Mills College. She worked on the 1972 presidential campaign of Shirley Chisholm, the first Black woman to hold a seat in Congress, and on Black Panther Party co-founder Bobby Seale’s mayoral race in Oakland the following year.
