There is a lot that Kenyan voters could be told that they have not been told about how their votes were represented to them by the IEBC over the last several days since they voted and all the ballots were counted Tuesday evening. As assurances given to the voters in 2007 and again in 2013 in the immediate aftermath of voting those years did not in some substantial respects turn out to be factually sustainable, it is no suprise many Kenyans would want to verify rather than just trust now.
One would expect everyone involved this year to anticipate questions. There were lots of prominently published warnings of the need for transparency (from the International Crisis Group among others).
Mr. Kerry was Secretary of State in 2013 and presumably has current clearances that would allow him as an individual, now post-government service, to make doublely sure he is fully briefed about the failed Results Transmission System of 2013, as well as other past problems, if he wasn’t before coming to Nairobi last weekend for the Carter Center. Presumably he could also ask the current US and Kenyan governments to go through the details relating to procurement and use of KIEMS this year. Then he could answer questions and demonstrate the kind of transparency that would build trust.
Alternatively Mr. Chebukati and the current U.S. government could answer questions irrespective of the Carter Center or other independent Election Obsevation Missions.
