Politics is a dirty game. Anything can be used for or against during campaign period.
Former Land CS Charity Ngilu and Kitui Senator David Musila have expressed interest in Kitui gubernatorial seat. This will be a hotly contested seat come 2017 as the incumbent governor will also be in the race. Rumours has it that Chief Justice Dr Willy Mutunga is eying for the same seat
Though age is just a number, it might be one common denominator that opponents will use to fight Musila and Ngilu who are 73 years and 63 years respectively (Source: Wikipedia)
