Deputy President William Ruto, ANC leader Musalia Mudavadi and his Ford Kenya counterpart Moses Wetang'ula on Wednesday stormed Baringo county.
The leaders held a mega rally in Eldama Ravine town where they drummed up support for their camp.
Thousands of area residents turned up at the rally in support of the leaders even as they affirmed the union of the three leaders.
"For those who are pitching a tent in hotels thinking that they will decide for us our future will be in for a rude shock," DP Ruto said.
The DP further spoke on his union with the ANC and Ford Kenya leaders saying their main goal is to change Kenya.
He said their unity is not about positions but about changing the economy of Kenya and uniting the country.
The Eldama Ravine rally comes barely a week after Mudavadi launched his presidential bid.
It is during the launch that he declared willingness to work with DP Ruto and said he will not work with ODM leader Raila Odinga.
The leaders are expected to proceed to Nakuru for a Mega Rally.
