I am sure if UMK and WSR were hell bent on rigging, they would not spend soo much time on the campaign trail.
But again, i would not take his allegations lightly as WSR once indicated there is no way they can loose now that they are in power. As they say, hakuna mwizi na mwenye kuchungilia, so both the thief and the bystanders are all thieves.
