At The Washington Post, Aaron Blake reports:
A new poll from the University of Southern California shows that although Feinstein and Boxer have image ratings that are much more positive than negative (by double digits), about six in 10 Californians (59 percent) would prefer that they not seek reelection. Just three in 10 (29 percent) say they should run again.
Nearly half of Californians -- 48 percent -- say they "strongly" want new people to run. Even among Democrats, 44 percent say it's time for new blood, while 43 percent say the two senators should seek reelection.
...Also note that the just-reelected Jerry Brown (born April 7, 1938 (age 76)) is the oldest governor in the United States,* and both the oldest and longest-serving governor in California history. What is more, a member of the Brown family was on the statewide ballot in 15 of the past 18 gubernatorial election years.
At least part of the reason for the call for a changing of the guards is undoubtedly that Feinstein and Boxer are among the nation's oldest senators. Feinstein is the oldest senator, at 81, while Boxer, who is 73, ranks 16th.
A few months ago, Alexander Burns noted at Politico:
The most prominent member of the congressional delegation, 74-year-old House Minority Leader Nancy Pelosi, started out as chairwoman of the California Democratic Party when Ronald Reagan was president. The current party chairman, 81-year-old John Burton, is a former congressman who first went to Washington in the 1974 post-Watergate revolution.
* Hawaii's Neil Abercrombie is also 76 but was born a few weeks later, on June 26, 1938. In any case, he will no longer be governor next year, as he lost his primary.
