President Uhuru Kenyatta has reiterated the only path to the presidency is through the ballot.
The Head of State warned that the Government would take action against Opposition leader Raila Odinga over violent protests.
Addressing Jubilee supporters at a campaign rally in Nyahururu town, President Kenyatta and his deputy William Ruto said the Constitution did not provide for a negotiated government.
President Uhuru warned he would not entertain any foreign interference in Kenya's internal affairs because, to the best of his knowledge, there was no political crisis that would warrant assistance from friendly foreign countries.
"If you are a foreigner and you want to come to Kenya as a tourist, you are welcome. Come visit our national parks and other tourist sites but we will not entertain interference in our internal democracy," the President said.

Uhuru said it was clear Opposition leader Raila Odinga, who has opted out of the fresh presidential elections, was only keen on the formation of a negotiated government.
"I want to tell Raila today; do not joke with the lives of Kenyans! The Government will no longer entertain violent streets protests that disrupt business and normal living. This Government will take action against you," he said.
"I repeat Kenya is not in any political crisis as Raila wants our foreign friends to believe. The only problem in Kenya is you, Raila. And if you are democratic enough, face me at the ballot," said a tough-taking Uhuru.
He told the NASA leader to respect the Constitution and allow Kenyans to go to the polls on October 26. Speaking in Karatina stadium, the President said it was Raila's decision to go to the courts and he should respect their decision to nullify the election.
"We had won in the August 8 poll, but we respected the court's decision. And we are going back to the polls, Odinga should prepare himself for the elections because the Constitution is clear," he said.
The Head of State said if Odinga was not interested in participating in the October polls, he should go home and let Kenyans go and vote.
"If you do not want to go to the polls, go home, but do not interfere with the right of Kenyans who want to exercise their democratic right to vote," He insisted.
Deputy President William Ruto said Mr Odinga had no choice but to respect the Constitution.
"This is not the animal kingdom, we are all equal and we will follow the Constitution, elections will be held on October 26 with or without you (Odinga)," He said.
Ruto said Raila was embarrassing the country abroad with claims that the country was on the brink of a constitutional crisis that would require external assistance.
"We told Raila in 2013, we repeat it today here again that there will be no negotiated government. No matter where you will go to lie about the situation of Kenya, we will not form a negotiated government. You are embarrassing Kenyans abroad," he said.
