MIA? She's all over the place- getting publicity and inspiring the electorate is key right now- not dry policy posted on a website- we largely know where she stands on most issues already anyway. she will largely support the usual Democratic policies and mostly keep to the Biden agenda with some tweaks I think
IMO plastering some policy bullet points these days will work against her- the right will nitpick and take that stuff out of context. Just look how fast trump ran away from Project2025.
More will come out at the convention and the debate.
