Luke Savage on Dems taking the politics out of politics. I think the below is a pretty good description of this phenomenon.

Lesser evilism has been an animating principle among American liberals for as long as I can remember, and it rather conveniently fails to disappear even after election seasons have concluded. Which is to say: Plouffe’s veil-of-ignorance approach may justify itself by invoking the exceptional danger of the Trump presidency, but the same exceptional danger was also said to be with us in 2000, 2004, 2008, 2012, and 2016. Democrats being preferable to Republicans, or so it follows, there’s little reason for the socially concerned person to ever do more than try and elect the former and dull any moral reservations about the kinds of things they regularly do when in office. Once this line of reasoning has been fully internalized, the whole enterprise of political and social activism as we know it becomes indistinguishable from unthinking partisanship for the Democratic Party and its leaders, the rank-and-file liberal reduced to little more than a campaign drone who blindly follows directives handed down from above. (Though there are many reasons centrist liberals have exhibited such a burning hatred for Bernie Sanders, his movement’s steadfast refusal to assume this hierarchical and deferential posture was undoubtedly among the most significant.)

This is the actual purpose of liberalism’s veil of ignorance: to subordinate policy, ideology, and even basic morality to the wider goal of pledging unthinking fealty to some Generic Democrat and keeping Republicans out of office. Tellingly, Plouffe’s supposed manual for a citizen’s crusade rarely even mentions actual issues and, when it does, it’s invariably in the service of helping elect said Generic Democrat regardless of their commitments or platform—which we do not know and in any case, we are told, do not matter (though the author did somehow know the Democratic nominee’s border and immigration policies in summer 2019, or more specifically what its necessary limits would be).
