New York Times: “In a year when House control could hinge on a handful of races, Republicans and Democrats alike have embraced a win-at-all-costs mentality. An all-out war to redraw House maps has consumed statehouses in recent weeks. But open primaries can impede such partisan gains, because they allow voters across the political spectrum to choose candidates, often resulting in centrist choices.”“Open primaries, the thinking goes, allow non-party faithful to vote — and run — which increasingly polarized party leaders see as a potential forfeit of power. They also claim that open primaries, and more complicated systems that let voters rank candidates, are confusing and unfairly reduce the influence of loyal party voters.”
