Feinstein’s Death Intensifies Fight for a Coveted California Senate Seat

The death of Senator Dianne Feinstein, the California Democrat, immediately turns the spotlight to an intense, ongoing three-way battle to replace her, fraught with racial, political and generational tensions over one of the most coveted positions in California and national politics.

It also puts new pressure on Gov. Gavin Newsom, who will chose someone to fill her term through the end of 2024. Mr. Newsom, whose profile has risen in national Democratic politics in recent weeks as he has traveled the country on behalf of President Biden’s re-election campaign, had come under fire for announcing he would not pick any of the declared candidates in filling any vacancy, so as not to elevate them and give them an advantage in the Democratic primary race.

Mr. Newsom had originally promised to pick a Black woman to fill the position if it opened up, and many Democrats thought he would turn to Representative Barbara Lee, a progressive. But Mr. Newsom said he would pick a caretaker senator instead. “I don’t want to get involved in the primary,” he said on NBC’s “Meet the Press.”

Ms. Lee denounced Mr. Newsom for that decision, calling it insulting.

The other leading Democratic candidates in the primary race for Ms. Feinstein’s seat are Representative Adam Schiff, a high-profile member of the congressional committee that investigated the Jan. 6, 2021, attack on the Capitol; Representative Katie Porter, a third-term California member of the House; and Ms. Lee.

It remains to be seen if, after Ms. Feinstein’s death, any other candidates will jump into the race. However, Mr. Schiff, Ms. Lee and Ms. Porter are well-known figures in Democratic politics, and have for months been raising money and building support.

It is unclear whom Mr. Newsom might pick to fill Ms. Feinstein’s seat for the remainder of her term. The names that have been discussed, since Ms. Feinstein said earlier this year that she would not run again, include Shirley Weber, the California secretary of state; Holly Mitchell, a Los Angeles county supervisor; and Angela Glover Blackwell, a civil rights lawyer in Oakland and the founder of PolicyLink, a research and advocacy nonprofit group.

Mr. Newsom had originally made the pledge about a Black woman in response to the fact that there are no Black women serving in the Senate. The last one was Kamala Harris, a California Democrat who left the Senate to become Mr. Biden’s vice president.

At that time, in January 2021, Mr. Newsom picked Alex Padilla, the California secretary of state, to replace her. Mr. Padilla became the first Latino from the state to serve in the Senate; he was elected last year to a full term.
