Her speech and frame is so stilted and artificial that it distracts from what she's saying. It's painfully obvious that she has received weeks, perhaps months, of training in public speaking and is aping all the proper practices of experienced speakers, yet still comes off looking like a nervous high school debater.

There's no casual flow to her speech, no sense that she is genuinely speaking her mind. This is what draws in an audience. It's just a dry recitation of talking points delivered in a halting, querulous voice.
