Agreed, it wouldn't change the outcome of elections -- but that is of utterly no political interest. The wrong questions are being asked (and the right ones will never be asked).
A question establishes (for most people) the relevant parameters of the answer. Questions about elections will gather answers relevant to elections. Such questions and answers tell us nothing about political views -- they focus attention on horse races rather than on substance.
Discussion of polls focuses attention on big numbers; everyone thinks that, for example, 1% is an insignificant figure. But 1% in B/N, for example, would mean around 1500 people. If only another 300 people would become active members of any of about 4 different small groups, we could turn this community upside down; we could have thousands on the streets.
>From the perspective of the only real politics, the politics of mass
movements and direct action, percentages under 5% represent a great deal of
power.
