Since you’re getting troll comments from right wingers I’ll try to give an actual answer
Feinstein was no longer mentally fit to serve in office. She was essentially the pre-cursor to a weekend at Bernie’s setup. She was not cognitively present enough to vote on legislation or even hold a conversation.
People are glad she passed because it means her seat is open to someone who can actually work on policy and benefit their constituents.
Liberals are not exactly a fan of letting the elderly die in office after the RBG situation that ended up with a stacked court when she had the option to retire under Obama.
Also Lemmy has definitely been having more right wing trolls recently and it’s making me want to use the platform less.
