So, I'm seeing OPs here already about replacing older leaders

169. the Senate chamber is a highly structured environment

and one where she has notes prepared by her staff. Outside of structured environments? Not so great, apparently.

WASHINGTON — When a California Democrat in Congress recently engaged in an extended conversation with Sen. Dianne Feinstein, they prepared for a rigorous policy discussion like those they’d had with her many times over the last 15 years.

Instead, the lawmaker said, they had to reintroduce themselves to Feinstein multiple times during an interaction that lasted several hours.

Rather than delve into policy, Feinstein, 88, repeated the same small-talk questions, like asking the lawmaker what mattered to voters in their district, the member of Congress said, with no apparent recognition the two had already had a similar conversation.

The episode was so unnerving that the lawmaker — who spoke to The Chronicle on condition they not be identified because of the sensitivity of the topic — began raising concerns with colleagues to see if some kind of intervention to persuade Feinstein to retire was possible. Feinstein’s term runs through the end of 2024. The conversation occurred several weeks before the death of her husband in February.

“I have worked with her for a long time and long enough to know what she was like just a few years ago: always in command, always in charge, on top of the details, basically couldn’t resist a conversation where she was driving some bill or some idea. All of that is gone,” the lawmaker said. “She was an intellectual and political force not that long ago, and that’s why my encounter with her was so jarring. Because there was just no trace of that.”
