President Uhuru Kenyatta and his deputy William Ruto are set to make their finally campaign tour at Afraha Stadium in Nakuru County in a bid to consolidate votes.
The Saturday tour comes a week after the National Super Alliance (Nasa) presidential flagbearer Raila Odinga visited the region in an effort to boost his popularity.
Nakuru County, which is at the heart of Rift Valley, is ranked third by the electoral agency in terms of registered voters.
Nairobi County topped the list with 2.2 million voters who will be eligible to vote, followed by Kiambu (1.18 million), Nakuru (949,618), Kakamega (743,736), Meru (702, 480), Machakos (620, 254), Murang’a (587,126), Mombasa (580,223), Bungoma (559,850), Kisii (546,580), Kisumu (539,210), and Kilifi (508,068), in that order in the top 12.
In all, the former Rift Valley Province, comprising 14 counties, has a total of 4,649,768, the single biggest unit with the most votes.
Turkana has 191,435, West Pokot 180,232, Samburu 82,787, Trans Nzoia 339,622, Uasin Gishu 450,055, Elgeyo Marakwet 180,664, Nandi 346,007, Baringo 232,258, Laikipia 246,487, Narok 341,730, Kajiado 411,193, Kericho 375,668, and Bomet 322,012.

The president and his deputy hold high regard for the county because it is where "Jubilee's roots can be traced".
The county is considered a Jubilee stronghold hold despite being a cosmopolitan.
The President will be seeking to stamp his authority in the region as well as emasculate any possible impact made by Nasa.
Thousands of supporters are expected to throng the venue is a show of solidarity.
Ms Dorcas Gachira, a resident, welcomed Mr Kenyatta's visit, saying it is a special occasion.
"We feel very happy that the president and his deputy have a high regard for this county and we are ready to welcome him back to his homeland," Ms Gachira said.
Among the issues the residents expect the President to address, she said, is security - considering the county has been mapped out as a violence hotspot.
Nakuru was also adversely affected by the 2007/8 post-election violence that say more than 1,000 people killed and others displaced.
Hence, some residents are fleeing to their rural homes over violence fears.
However, police have assured Kenyans of their safety.
