In democracies, the opposite is true: the winning
coalition is large, and the real selectorate is
almost as large as the nominal selectorate. This
means that dictators can keep their jobs by
handing out private goods to their cronies,
whereas democratic leaders have to dole out
public goods to maintain their power. That
seems to square pretty well with observations
in the real world.
I'm not sure how to square this with recent US elections, where poorer folk increasingly vote for the party that openly pledges to give them the least, at least in tangible terms.I suppose that "dole out public goods" doesn't necessarily have to apply to tangible goods, of course. A lot of Republicans are happy to vote for Republicans simply because they have promised to ban things they find objectionable, like abortion. If preventing women from having abortions is one's biggest personal issue, then I suppose a guarantee to curb abortion rights would be seen as "public goods."
