This is a fair take; I happen to be of the opinion that getting Democrats to vote in every election is a much more effective and immediate fix than anything else on the table, but I could be wrong:
One final thing Hillary cannot say, but which many Democrats intuitively grasp, is that her nomination lets her party postpone a reckoning. The Republican coalition has broken apart, blown up by leadership duplicity. Democrats are in better shape, but they still have considerable fissures of their own. Their party elite favors globalism and free trade; their non-elite prefers more nationalism and protectionism. In papering over these splits, the Obama coalition has focused increasingly on civil rights injustices related to gender or race. But this is an unsustainable approach, further alienating white working-class voters and fostering internal squabbles over who deserves what. Only the fear of a common foe, the GOP, keeps the peace. Bernie Sanders, by shifting the focus away from identity and over to economic justice, is inviting Democrats to have it out. Hillary Clinton, by contrast, is inviting Democrats to keep it in. Even if she’s not a natural unifier, she embodies the idea of “Democrat,” and that spares people from having to examine it more closely. Political parties don’t like to think, and with Hillary Clinton they don’t have to. Maybe there’s a Clinton campaign t-shirt in that: Don’t overthink it. Just vote Hillary. Or maybe not. But it doesn’t matter. Either way, the outcome is the same: she wins.
