Of course, there will be some rigging and misuse of government machinery. But given that Kenyan voting is all about "our people", rather than issues, the basic numbers favour CORD, and they could have made things more difficult by registering large number of voters and then ensuring that they vote. If CORD leaders have learned anything about the former, it must be a "deep" secret. Too much time and energy were instead misdirected into the funny business known as Okoa Kenya. So, as things stand, they will again be tyrannized by numbers from a smaller base.
Saying that there will be rigging or other bad behavior will not prevent it. Threatening violence, implicitly or explicitly, won't work: in Kenya, as in most of Africa, whoever controls the state machinery wins in any round of electoral violence.
