No, 2020 was unique in that in the general election, there was little talk of American ventures overseas. A product of that is Bernie Sanders losing in the primary and there being more attention-raising issues with Covid and the protests, but the fact that both candidates advancing to the GE are very much not anti-war is something as well.
How is Bernie losing a product of voter sentiment on our overseas ventures? Both of his primary runs had little spotlight on foreign policy.
I think it's more the Democratic Party as a whole (And the GOP, gradually so) putting less emphasis on foreign policy over the last few years.
