Winning an election is as easy
as making githeri!

If any the leading presidential candidates can
attract 50,000 supporters to their respective campaign launch rallies,
are the recent opinion polls credible in indicating wide gaps in the
popularity of the aspirants?
To understand what is going on, suppose you were
making some githeri. After
mixing the maize and beans in the pot, how would you determine the ratio
of the seeds quickly?
You can scoop out a cupful of the mixture and count
the number of maize and beans. Then the ratio of the seeds in the cup
would be the same as that of those in the pot. This method is similar to
an opinion poll: You scoop out a cupful (small sample of respondents)
and use the ratio of seeds (candidate preferences) in the cup to
determine the ratio in the pot (the whole population).
Now suppose further that you have already mixed the
maize and beans in the pot and before putting it on the fire you
remember that you need a cupful of beans for another meal. How do you
that get them out of the mixture? It’s easy; you carefully select the
beans (one-by-one) and put them in the cup…until it fills up.
This is similar to a political rally for one
candidate: only the desired type of seed (the people who support that
candidate) goes into the cup (the rally venue). As demonstrated last
week, the Nairobi venues take about 50,000 people – that’s an easy task
for the main presidential aspirants.
Now we have seen an opinion poll and a political
rally, but how would the githeri
simulate an election? Well, suppose you have mixed the seeds in the pot
– with more maize than beans (by the way, this makes better
githeri!)
Then you call two people and ask one of them to pick
out the maize and the other the beans in a duration of, say, 30 seconds.
The time limit is important because it will ensure that they don’t empty
the pot.
Now, although there is more maize than beans in the
pot, the person picking the beans could have faster fingers and
therefore end up with more seeds at the end of the exercise. This is
what happens in an election – the candidate who can get more of his
supporters to go out to vote (faster fingers) wins. (I once won an
election with only 10 percent support!) For this reason, some
statisticians contend that a random sample opinion poll is a more valid
measure of preference than an election.
This also explains why politicians give money to
voters on Election Day. It is not a bribe to change their choice. No.
The cash is given to supporters – not to the opponents! It is simply
compensation for going to the queue to vote. Remember, this is a country
where half the population survives on less than Sh60 per day. Spending
Sh1,000,000 can easily get a politician 10,000 votes (Sh100 each) –
enough to win a parliamentary seat!
