There’s also evidence in the report that young religious voters of color in particular may feel less loyalty to the Democrats than older generations did. Only 35 percent of Hispanic Catholics under the age of 30 identify as Democrats, compared to 56 percent of Hispanic Catholic seniors. Similarly, just 58 percent of black Protestants under 30 say they’re Democrats, compared to 79 percent of black Protestants over the age of 65.and Republicans:
So far, having a base that’s composed overwhelmingly of one demographic group hasn’t doomed Republican candidates — white, conservative Christian voters have been the bedrock of the GOP base since the 1980s and helped deliver President Trump to the White House last year. In 2016, a whopping 35 percent of Republicans were white evangelical Protestants, 18 percent were white mainline Protestants, and 16 percent were white Catholics; together, those groups account for nearly 70 percent of the Republican base.To me, the most interesting aspect of the report is the age breakdown of the "religiously unaffiliated" (which I would call "the godless"). The results are 34% are age 18-29, 37% are 30-49, 19% are 50-64 and 10% are 65+.
