WARREN, Michigan — Former President Donald Trump appeared to be tamping down his campaign’s overconfidence that he will win the election during a Friday rally at Macomb Community College in Warren, Michigan, where he cautioned against reading the tea leaves of preelection data.

“You gotta vote. Don’t believe the polls that we’re way up,” Trump admonished the crowd. “One gentleman — a great pollster, they say — he said we have a 97% chance of winning. I said, don’t believe it. Don’t believe it. I think he’s a Democrat because nothing matters except what happens on Tuesday when you think of it.”
