A research company conducted a survey to determine the attendance of registered voters in a series of campaign rallies conducted by three aspiring candidates, Abigail, Benson and Charles, in a small but crucial ward in Nairobi. Among the 1500 registered voters interviewed:
-
650 attended Abigail’s rally
-
550 attended Benson’s rally
-
780 attended Charles’ rally
-
250 attended both Abigail and Benson’s rallies
-
350 attended both Abigail and Charles’ rallies
-
280 attended both Benson and Charles’ rallies
-
130 attended rallies of all three candidates
-
The survey revealed voter apathy noting that quite a sizable percentage of those polled did not attend any of the rallies.
