God gap
n.— «Why is there so much fascination with the so-called God gap, the finding that the more religiously observant Americans are, the more likely they are to vote Republican? Or, to put it the other way round, the more secular Americans are, the more likely they are to vote Democratic?» —“In Politics, the ‘God Gap’ Overshadows Other Differences” by Peter Steinfels New York Times Dec. 9, 2006.
