Sources say campaign is concerned that Trump may engage in the kind of self-sabotage that turned off voters in 2020

Donald Trump’s campaign is most concerned going into the debate against Kamala Harris with the former president’s mood, afraid that the mercurial Trump could engage in the kind of self-sabotage that turned off voters in the 2020 presidential election, according to people familiar with the situation.

The campaign’s internal refrain is whether they get “happy Trump” or “angry Trump”, the people said, as they count down the days to perhaps the final presidential debate this cycle.

Tuesday night’s televised debate is widely seen as a crux moment in the rebooted 2024 campaign. Since Joe Biden dropped out of the race after a campaign-killing debate performance crystalized fears over his age and mental acuity, Harris has turned the race on its head.
