Others also billed for the seat include Narc Kenya leader Martha Karua, Agriculture CS Peter Munya and former Gatanga MP Peter Kenneth.
The Issue of a running mate is proving to be a political hot potato in both the Azimio La Umoja One Kenya Alliance and the Kenya Kwanza camp led by deputy president William Ruto.
A number of leaders have positioned themselves as potential running mates giving the top seat candidates a headache in choosing a suitable candidate.
The Independent Electoral and Boundaries Commission on Tuesday extended the deadline for the submission of a running mate candidate to May 16.
IEBC chair Wafula Chebukati also said Governor seat candidates will also be required to unveil their deputies by the same date.
