“It’s unfair that I beat Joe Biden and now they have to beat you too.” These were the words Donald Trump vented in recent days to a friend, expressing clear nervousness and anxiety about the entry into the field of Kamala Harris, who, in just a few weeks, has turned a game that he and the Republicans considered closed and won it. Less than a month ago, Trump, who survived the assassination attempt on July 13, had received the strong and enthusiastic support of the party at the Republican Party convention, blocked many of the legal proceedings against him, and was flying high in the polls in the United States. Facing increasing weakness, Biden faces difficulties.

“At the convention, the game was over, and the Democrats realized it,” Richard Porter, a Republican committeeman, told the Washington Post, but then admitted, commenting on the background: “It seemed too good to be true, and it was. It’s incredible how quickly they rallied around the new nominee.” If Trump had been calling the potential vice presidential nominee “pathetic” a few weeks ago, since July 21 — the date of Biden’s resignation — his advantage has shrunk, and now the race for the White House is effectively a head-to-head.
