Democratic vice presidential nominee Kamala Harris said in Detroit Tuesday that Americans concerned about the potential for unrest as polls close on Election Day should “have faith in the American people.”

“I do strongly believe that we, whoever we vote for, will defend the integrity of our democracy and a peaceful transfer of power, and that there are certain lines that, whoever you vote for, that we just won’t cross,” Harris said.

Harris, a U.S. senator from California, was in Michigan for a last minute blitz of the Detroit area as voters went to the polls. 

Harris made two unannounced stops, one at a canvass kickoff in Southfield and another at a polling place in Detroit. 

Harris was joined at the Southfield event by U.S. Sen. Debbie Stabenow (D-Lansing) and U.S. Sen. Gary Peters (D-Bloomfield Twp.). 

Harris vouched for Peters, who is locked in a tough re-election battle with Republican businessman John James, saying that he helped her find the ropes when she was first elected to Congress and noting that they were seated near each other in the chamber.

“This is who Gary is,” Harris said. “When we sit in these rooms, when there are no cameras or there are cameras, Gary is always fighting for Michigan. And it’s going to be a tight race.”

Harris encouraged voters to make sure their friends and family are also voting.

“You know, in Michigan, the last election for president in 2016, the outcome of that election was decided, on average, by two votes per precinct in Michigan. Two votes,” Harris said. “Can you imagine if each of us just pulled out another two people to make sure they voted today? It could determine who will be the next president of the United States of America.”

Polls across the state are open until 8 p.m. More than 3.1 million Michiganders voted before Election Day.
