A think a lot of it is that we're no longer in the 'miracle' phase of when Biden dropped out and the campaign assumes she's got the base as locked in as it's gonna get and is going after undecides/Haley votes, which understandably takes the wind out of everyone's sails. It feels very...normie-Dem.

I think the big issue is overestimating the value of carving off marginal Haley voters at the expense of losing base enthusiasm when that's useful for turnout or "hey we need people to write postcards"
