Tara Palmeri: "Despite the endless and voluminous and ubiquitous polling suggesting that we are careening toward a historically tight election, Donald Trump can only see an outcome in which he wins. Inside Mar-a-Lago, I've heard that Trump is uncharacteristically buoyant, almost cavalier, convinced that victory is his."

"Yes, some in Trump's orbit are concerned about displaced voters in North Carolina, but the only thing that the former president believes could cause him to fail, I've been told, is if the Republican National Committee election integrity unit -- which includes at least one 2020 election denier -- fails him."
