Deputy President William Ruto has once more appealed to president Uhuru Kenyatta to spare him the political firepower he has unleashed lately.  in his message, Ruto says the president should allow him to square it out with Azimio la Umoja presidential nominee Raila Odinga? man to man.  the question is, did the UDA party leader underestimate President Kenyatta who he seems to have christened lame duck too early? is the DP already feeling the heat... less than a month after the president declared a bare-knuckle politics contest against him? Duncan Khaemba tries to join the dots.
