Wow, I’ve never thought of this situation quite this way, but it totally makes sense: John Stoehr argues that Biden let the press corps define him and his campaign (He’s too old, he’s confused, etc.) by making it about vibes and not about substance. Kamala is not giving the Washington press corps unfettered access, engaging them if and when she chooses, thus refusing to let them define her the way they want to. And it’s driving them nuts.
Vibes are this press corps’ forte, not fact and substance. If fact and substance were its strength, there would have been a different reaction to The Disaster Debate during which Biden talked about policy and issues while Trump didn’t bother. Trump was incoherent and false, but he came off as confident and strong, and he came off that way, because the press corps’ forte isn’t fact and substance.
Now that she’s in the race, her campaign is being judicious and strategic about what she says to whom, and it’s working.
This is a democracy. Harris is obliged to talk to Americans. That’s the end of her moral and democratic obligation. She’s not obliged to talk to the press corps, as if it were a constituency.
