Still, he added, “Men are men. You never know what they do.”
Throughout his campaign, Mr. Odinga roused supporters by warning that the election could be stolen, which critics say is an incitement to violence. He says he was robbed of victory in the previous two contests. In 2013, Mr. Kenyatta won by a margin so tiny that Mr. Odinga asked the Supreme Court to invalidate the election, although his effort was unsuccessful.
“They’re always cooking up results,” said Beatrice Akinyi, 34, referring to Mr. Kenyatta. “Right now, they’re being cooked somewhere between here and the national tallying center” to where the results are transmitted, she said.
Mr. Kenyatta and Mr. Odinga were virtually tied in recent polls, but neither is drawing more than 50 percent. If no candidate crosses that threshold, there will be a second round. Voters will also be casting ballots for members of Parliament, governors and local offices.
Given the tightness of the presidential race, the concerns expressed by Mr. Odinga increase the chances of opposition supporters protesting in the streets, followed by a crackdown by security forces. In 2007 and 2013, residents of Kisumu said they saw the police fire live ammunition into crowds of opposition supporters after the election.
