Orange Democratic Movement party leader Raila Odinga's son Raila Junior on Tuesday took a swipe at McDonald Mariga's supporters who had visited Karen.
Deputy President William Ruto hosted a delegation mainly from Abagusii community who live in Kibra, in a move targeting to dislodge ODM dominance in Kibra.
Mr Mariga was fronted by DP William Ruto in the race to succeed Ken Okoth, who died in July. ODM has backed Okoth's brother Imran Okoth for November by-election.
There were reports on Tuesday that a number of youths were locked from accessing Dr Ruto's Karen office, forcing some of them to hold brief demonstrations outside the office.
And Mr Odinga Junior wondered why the team was protesting yet Jubilee has reportedly been claiming that it has gained grounds in Kibra constituency.
"So why are “jubilee" youth demonstrating outside DP's official residence after they failed to secure what they had been promised, didn't they say Mariga is to win this one clean ama Kwa ground vitu ni different? he wrote.
The delegation of Abagusii was Lee by nominated Senator Millicent Omanga, Kisii Deputy Governor Joash Maangi and South Mugirango MP Sylvanus Osoro.
Dr Ruto said the government will focus on implementation of housing plans in the Kibra constituency, adding that the region will be a major beneficiary.
"Kibra and other informal settlements in Nairobi will be among the major beneficiaries of the government’s housing plan under the Big Four Agenda.
"It is therefore incumbent upon leaders from the area to ensure this affordable and decent shelter dream for every Kenyan is realised," he said.
On Sunday, nominated MP Maina Kamanda, who is campaigning for Imran, asked Kibra residents to pitch tent at Ruto's residence so that they 'can get their share'.
Others in the race include Raila's former aide Eliud Owalo of Amani National Congress party and Eng Ramadhan Khamisi of Ford Kenya party.
