It's a wonder democracies function as well as they do:
...Voters have fairly short memories, and they judge economic policy not by long-term results but by recent growth. Over five years, the coalition’s record looks terrible. But over the past couple of quarters it looks pretty good, and that’s what matters politically.
In making these assertions, I’m not engaged in casual speculation — I’m drawing on a large body of political science research, mainly focused on presidential contests in the United States but clearly applicable elsewhere. This research debunks almost all the horse-race narratives beloved by political pundits — never mind who wins the news cycle, or who appeals to the supposed concerns of independent voters. What mainly matters is income growth immediately before the election. And I mean immediately: We’re talking about something less than a year, maybe less than half a year.
This is, if you think about it, a distressing result, because it says that there is little or no political reward for good policy...
