A large majority of Protestants (71%) – including 82% of white evangelical Protestants – say they would be less likely to support a candidate who does not believe in God. Catholics would view an absence of belief in God less negatively (48% less likely), while only about a quarter (24%) of the religiously unaffiliated say they would be less likely to favor a candidate who does not believe in God.
A candidate’s identification as an evangelical Christian or Catholic would not matter to most Americans. About one-in-five (21%) would be more likely to support an evangelical Christian; 17% would be less likely and 58% say this wouldn’t be a factor. However, most white evangelical Protestants (58%) say they would be more likely to support a candidate who shares their faith.
A substantial majority of the public (81%) say it would not matter to them if a presidential candidate is Catholic. Among Catholics, 23% would be more likely to support a Catholic candidate, while 72% say it wouldn’t matter.
There is a sizable partisan divide in views of a candidate’s religion. For Republicans, a candidate being an evangelical Christian is a net positive (36% more likely, 5% less likely); for Democrats, more say it would decrease (27%) than increase (12%) their chances of supporting a candidate.
And while 70% of Republicans say they would be less likely to support a candidate who does not believe in God, Democrats are more ambivalent: 42% say they would be less likely to support an atheist, while 49% say it wouldn’t matter to them.
