Vernacular not the cause of tribalism

I disagree with the sentiments expressed by Paul Maina in an article The Standard published on February 27, 2017. Mr Maina said vernacular had enhanced tribalism in the country.

There is no need to bar politicians from using their mother tongue at public rallies as long as they remain responsible. Political campaigns are about persuasion and connecting with the audience in a language that reverberates well with the subject.
