The proliferation of opinion polls on the presidential election makes it seem more like a sport involving personalities, when what these surveys should be doing is targeting policies

In Washington DC, I measure out my life in polls and heart palpitations. The polls are relentless, nail-biting, maddeningly contradictory. There are national polls, swing state polls, polls from tiny counties that predict a whole election, partisan polls designed to demoralise the other side.

There are polls on whether a candidate inspires confidence, compassion, leadership. I’ve noticed how, after a bad poll, I start looking for another that tells me numbers I like. I’ve also noticed how, after a good one, I will look for a bad poll to bring me down, as if I’m trying to prick the balloon of self-confidence and remind myself of “reality”.
