I wouldn't project it into a progressive lens, at least not first.

You need to contextualize the moment Hillary' and the country are in 2008-2016. There had been an anti-war movement as soon as the war plans were announced, but it was dutifully ignored by corporate media, in accordance with American tradition. The American economy was being swept by the peak of the "great-recession", occupy wall street happens around this time. But that energy really doesn't get funneled into electoral politics until much later. It was grass-roots, outside power almost exclusively in the context of that time. Many of the leftist orgs that are now considered passe would have been avant-garde in that time (code pink etc). And keep in mind, Hillary was an opponent of Obama. She lost an election, and badly, speaking like this.

Political Progressivism as we understand it today doesn't really become a thing in the US until Bernie taps into that occupy wall street energy (really, as a direct effect of the both hope given to, and subsequent failure of, the Obama administration) and funnels it into electoral politics.
