Trump's supporters are also less devoutly religious than many other Republicans. Among all GOP voters, 42% say they attend religious services at least once a week. Among Trump's backers, 32% do so. At the other end of the spectrum, 37% of Trump's backers say they seldom or never attend religious services, compared with 30% of the GOP as a whole.

Among backers of other candidates, the figure is much loser. Only 15% of Rubio's supporters, for example, said they were that certain of voting for the Florida senator. Among Republicans as a whole, the figure was 35%.
