Why is DP Ruto too sure of winning elections?

I am not a psychologist or a discourse analyst, but if you have observed the body language of DP William Ruto, you will realise he is a man confident of winning the coming elections. 

Is the man under high-level training in the science of campaign messaging? I have in the past argued in this forum that Ruto has created a fictional persona recasting his public image as an iconic figure and a driver of our politics. A saviour from our economic mess. At some point a year ago, he turned his official home in Karen into a ‘small State House” where he would receive delegations singing allegiance from all over the country.
