Wiper party leader Kalonzo Musyoka is among the top politicians who have declared their interests in the 2022 presidential seat.
Kalonzo has maintained that he has what it takes to ascend to power in 2022.
As Kalonzo eyes the top seat in the next polls, he is facing a political rebellion in Ukambani.
A section of political leaders from the region has openly asked the former Vice President to resign and hand over the leadership mantle to young leaders.
Kalonzo's other nightmare in his race to succeed President Uhuru Kenyatta in 2022 is whether legible voters in his backyard are registered.
Kitui Governor Charity Ngilu argues that Kalonzo must rally his supporters to register as voters to increase chances of ascending to power.
Speaking in Makueni during the funeral of the late Francis Maliti Mwewa, husband to Grace Mwewa, former nominated MP on Saturday, Ngilu promised to support Kalonzo's presidential bid if he rallies Kamba's to register as voters.
Ngilu warned that Kalonzo's bid will flop if he does not rally his supporters to register.
Ukambani has in the last two general elections rallied behind the opposition.
In the 2013 and 2017 general elections, the region overwhelmingly voted for Raila Odinga and Kalonzo.
Ukambani is among regions with rich numbers in terms of voters.
Kalonzo enjoys massive support in Kitui, Machakos and Makueni Counties.
Political analyst Peter Ngure says Kalonzo is still the 'master' in Ukambani, despite the raging rebellion against him.
Ngure, however, notes that Kalonzo needs to stamp his authority and unify the region to vote in one basket in the much anticipated 2022 polls.
