I don’t get the problem. This is a factually correct description of Harris’s campaign strategy. And it’s absolutely the strategy she should be following.
The choice right now is: the old weird guy, with jaw-droppingly horrifying policy, and his frat boy vice-president; or the woman who isn’t old or weird, and her charmingly cuddly new vice president. Introducing policies that have the potential to lose independent voters isn’t a vote-winning strategy at this point. The winning strategy is to stick to policy announcements that are as uncontroversial as possible, while still assuring Democrats that she is one.
This is a case of journalists doing exactly what they are supposed to do.
