Who's more charitable, conservatives or liberals? Short answer is, neither; long answer, conservatives give more overall, but MIT is sure it's because they're richer.
"My Sunday column comparing private philanthropy and government social programs has revived the old debate over who is more charitably inclined, conservatives or liberals? Skipping to the last page of the story first, the answer is neither: As two MIT political scientists determined in a 2013 paper, the inclination to give appears to have virtually no relationship to one's partisan or ideological views. There are distinctions, however, in the kind of giving between the two poles." -- Michael Hiltzik, the Los Angeles Times
