Campaign Messaging in Sheng, Swahili and Mother Tongue
Swahili is for messages that have to reach everyone. Sheng works with young urban voters who speak it every day, and a mother tongue brings warmth and trust in the home area. Write each message in its language from the start instead of translating it, and test it on native speakers before it goes out. One rule covers all of them: if you would not say it in English on the evening news, do not say it in any language. In 2026 the National Cohesion and Integration Commission summoned several politicians over remarks made in public, and with a phone in every hand, each rally is being recorded.
What each language does
Swahili is the national language, and every Kenyan audience expects it at a rally. The big lines go in Swahili. On 30 August 2026, after police fired teargas at the Linda Mwananchi rally in Makutano, Meru, Edwin Sifuna (Senator, Nairobi) told the crowd: "Hakuna siku teargas itamaliza mkutano wa Linda Mwananchi." A line like that travels because everyone understands it.
Sheng belongs to young, urban Kenya and it moves fast. Used well, it tells listeners the candidate is one of them. Used badly, or a year out of date, it makes him look like he is trying too hard. It sounds best coming from young supporters on TikTok and WhatsApp, and less natural in the candidate's own speech. Our guide on TikTok as your county's news channel covers the channel.
A mother tongue is the language of the home, of burials and of family meetings. Speak to elders in theirs and you earn a kind of trust English cannot buy. It is also where the most dangerous remarks tend to be made, because speakers assume only insiders understand them.
Every word is recorded and translated
The NCIC's summonses in 2026 show how public remarks are now treated.
On 1 September it summoned Joseph Ole Lenku (Governor, Kajiado) to appear on 17 September. The summons concerned his remarks on 22 August that parties fielding a non-Maasai candidate for "a position meant for the Maasai" would have "no relationship" with the community. The commission also summoned Nominated MP Joseph Wainaina over remarks at Ngeria, Kapseret, on 29 August, and John Ariko Namoit (Turkana South) over remarks about the Pokot community made at Kaputir on 2 September.
In a separate case, John Kaguchia (Mukurweini) was arrested on 3 August 2026 over remarks at a Kieni rally that Ruto supporters would be "smoked out", The Star reported.
A summons decides nothing about guilt. It still costs time and legal fees, and it brings headlines. Our explainer on ethnic contempt as an election offence sets out where the legal line sits.
Writing in the language
A slogan drafted in English and run through a translator reads like a government notice, so start in the language you mean to use. Then try it on native speakers of different ages. Idioms that land with elders can mean something else to the young.
Plenty of insults in Kenyan politics started life as innocent words. Ask your testers what a rival could make of the line. And keep an English version on file, so that if a clip is challenged you have the exact words and an accurate translation ready.
Assume the whole country is listening
Anything said in a mother tongue can be clipped, subtitled and posted within an hour. Nicknames for rivals, jokes about communities and coded words about "outsiders" are the lines that end up before the NCIC.
Barbs aimed at opponents shape the mood of a crowd too, whatever the language. Touring Bomet and Kericho in September 2026, President William Ruto mocked opponents as taking advice from "waganga", and Sifuna answered him in Nairobi on 13 September. Sharp exchanges between politicians are normal. The trouble starts when the target is a community.
For campaign staff
Every surrogate who speaks for you should get a one-page brief in each language they will use, with three messages and three things never to say. Our guide on handling hecklers covers the moment a speaker is most likely to forget it. Fabricated clips are a separate risk; see deepfakes on the 2027 ballot.
Frequently Asked Questions
Can politicians campaign in their mother tongue in Kenya?
Yes. There is no ban on using any language. What the law prohibits is hate speech and ethnic contempt, in any language, and the NCIC investigates such remarks.
Which politicians did the NCIC summon in 2026?
They included Kajiado Governor Joseph Ole Lenku, Nominated MP Joseph Wainaina and Turkana South MP John Ariko Namoit, each over public remarks made in August or September 2026.
Should campaign slogans be translated from English?
It is better to write them in the target language from the start and test them on native speakers of different ages, checking for double meanings.
