Your scenario is perfect conjecture. What makes you think that the economy will collapse. Do you really think that he is running without giving it thought and having no "outside" support? Isn't it the same way people say if RAO becomes president Kenya will go to the dogs yet there is no concrete evidence of the same? Have any of the so called development "partners" indicated that they will no longer support Kenya if any of the two win the election?
There are people here who will vote for PK yet his chances of clinching it are very minimal and they don't count it as a wasted vote. I too see no reason why i cannot choose the candidate I prefer without having to explain and justifying myself. For instance the holier than thou RAO brigade will take the slightest opportunity to throw mud on UK's candidature forgetting that we are actually in this predicament as a result of the "stolen" election. Everyone is entitled to his choice and thereafter majority wins in a democracy hence my live and let live policy. Its a simplistic way of thinking but am comfortable with it, you should too.
