It sounds like you need to do some research about California politics.
Feinstein is by no means untouchable. And more of her support comes from Hollywood and old media than from SV. However, she does have a core in San Francisco given that's where she wound up as mayor stemming from the Moscone–Milk assassinations.
California has jungle primaries so winning the primary isn't enough. In 2018, this meant that the main election was between two Democrats--Feinstein (54.2%) and de León(45.8%). This was actually a pretty solid result given that Feinstein is a strongly entrenched, party supported incumbent. And it was actually the closest election since her first.
And 2018 was just the start of the progressive wing of the Democratic party getting started (that was the year that AOC got elected and surprised everybody), so a highly liberal challenger simply wasn't in the cards, yet.
She will have a much tougher road in 2024, but I will be highly surprised if she even runs.
My SV comment is not that the proles (that includes tech workers) in San Fran care for her, but tech power in SV is allied with her from a decades long symbiotic relationship.
The only time I agreed with her was her torture work, but that revealed her hypocrisy.
So, on the whole, I disagree with her and I believe her to be a massive hypocrite.
You don't mind the senators that voted to disenfranchise the millions of voters in Arizona?
In case I have to spell it out for you, yes, OP can simultaneously disagree with Feinstein and with multiple other politicians.
That's not what they said. They said Feinstein was worse.
A < B and A < 0 doesn’t imply B>0. All it implies is that A<B
Help me understand your logic here.
However, it doesn't follow from:
“Feinstein is the senator I dislike the most”
That I don’t mind the other 99, or any subset thereof.
She cant loose the elections because shes a Dem from CA. She cant get primaried because shes in the hands of the SV
