Republicans have been extending dominance among white Protestants

A few weeks ago the Democratic National Committee passed a resolution regarding the religiously unaffiliated. In it, the committee contends that “the religiously unaffiliated demographic represents the largest religious group within the Democratic Party.” It was seen as an attempt to solidify a growing portion of Democratic voters.

But could that resolution turn off another important voting bloc, namely, white Protestant voters?

Probably not—in large part because most white Protestants are already Republicans. Almost every predominantly white Protestant denomination—from Southern Baptists and United Meth­odists to Missouri Synod Lutherans and the Assemblies of God—is solidly Repub­lican, according to data from the 2018 Co­operative Congressional Election Study.
