Most Democrats — 76 percent — are absolutely certain or fairly certain about their belief in God, according to a 2018 study conducted by the Pew Research Center. That’s not a small number, although it is lower than the percentage — 90 percent — of Republicans who say they are absolutely certain or fairly certain about their belief in God…
But it is the subject of the religiously unaffiliated that has attracted widespread attention recently.
Most people — 54 percent — who identify as religiously unaffiliated identify as Democrats or left-leaning, according to Pew. About a quarter of the group claim to be Republicans or right-leaning.
Pew stated: “In the U.S., belief in a deity is common even among the religiously unaffiliated — a group composed of those who identify themselves, religiously, as atheist, agnostic or ‘nothing in particular,’ and sometimes referred to, collectively, as religious ‘nones.’ Indeed, nearly three-quarters of religious ‘nones’ (72%) believe in a higher power of some kind, even if not in God as described in the Bible.”
