Religious affiliations of presidents of the United States

Religious affiliations can affect the electability of the presidents of the United States and shape their stances on policy matters and their visions of society and also how they want to lead it. While no president so far has ever openly identified as an atheist, Thomas Jefferson, Abraham Lincoln, and William Howard Taft were speculated to be atheists by their opponents during political campaigns; in addition, a survey during the first presidency of Donald Trump showed that 63% of Americans did not believe he was religious, despite his professed Christian affiliation.
