The author’s mistake here is the conflation of anecdotal evidence with a broader, intractable sentiment among Democratic primary voters, 58% of whom have supported Clinton so far.
If history is any indication, the vast majority of “Never Hillary” voters will come around. That is, if they were ever serious about voting in the first place.
At this point in the 2008 primary, over half — HALF! — of Clinton supporters said they weren’t even somewhat likely to vote for Obama in November. Ultimately, 89% of Democrats voted for him in the largest general election turnout in 40 years.
Emotions run strongly in competitive races, as 2008 clearly indicated. That’s a good thing. Engagement and excitement is an important part of the democratic process, even in candidate-specific campaigns.
But I suspect most progressives, Democrat or Independent, understand the stakes in this election aren’t merely high, they’re stratospheric. Anyone wishing to not see a Republican name Antonin Scalia’s replacement on the Supreme Court and undo every inch of progress made in the last seven years will very probably see reason on this.
