The 2024 Trump presidency won't be bad.
He'll implement various pro-American policies, do his best to bring peace to east Europe and the Middle East, make the right economic decisions, and reduce the number of illegals in this country (but probably not enough).
The threat to the country will come from the reaction from the left. There will be riots, either in the immediate aftermath of the election or because of the most minor of incidents (ex: life time criminals dying of overdoses while resisting arrest).
The heavily-left MSM will continue to create non-stop North Korea-level propaganda that will instigate the most easily agitated and will depress otherwise normal Americans.
Crime in blue cities will continue to rise as local mayors/DAs allow, aid, and abet the behavior (happened in my city during Trump 45 and "magically" disappeared when Biden was installed).
Summarized, a good portion of the population 30-40% will experience a mass mental breakdown event, brought on by their own misguided emotions and the propaganda media, and they'll continue doing stupid and harmful things to themselves and the community around them but at an accelerated rate.
