If you ask someone who's actually going to fight for universal health care whether they plan to fight for universal health care, the answer is simply "yes", or maybe that with a small bit of embellishment like "yes; it's the only sane thing to do; it's the only sensible thing to do" or "yes, and the perfect program with which to do it is already running, so all it would take is taking away the restrictions on who can use it". But she never says anything like that.
Instead she keeps starting off with one of her lame "reframings" ("first of all, let's be clear about what the issue here is, and it's not really what you just asked about...") about how all Democrats really want the same thing and those whose actual answer to the question is "no" are really just the same as the ones whose answer is "yes", then wandering off into a ramble through a list of "ways to do it" (where "it" has been "reframed" as not actually universal health care anymore) in which every item on the list is nothing but a way to avoid universal health care and stick as close as possible to preserving the current travesty for as long as possible. It ends up so full of weasel-words that she's clearly just setting up her defense for later; a few years from now, when she's President and still hasn't actually done a thing on this issue, she'll be able to point back to these verbal meanderings and remind people that she never really even said she would do anything in particular.
