I had to cut a bunch to keep it to 25. The list is a Venn diagram overlap of "my top reasons" and "reasons aimed at moderates, independents, uninformed voters, and younger voters who may not have experienced his 1st term as the rest of us". Broken down into 4 categories.

Patriotic

1. Tried to overthrow the US government by lying that he has evidence that the election was stolen from him in multiple states. Produced none of the evidence, admitting in court that "this is not a fraud case, we are not alleging the election was stolen."¹ Marched on DC with a belligerent mob fed months of conspiracy theories and told them to march on the Capitol. Was silent for hours as his mob attacked the Capitol in order to stop the official certification of the transfer of power.
2. Continues to lie that he won the election and that the election was stolen, therefore disrespecting democracy and instilling an unwarranted and dangerous skepticism that divides people along Earth-1 and Earth-2 over complete nonsense no evidence lies.¹
3. Stole Top Secret documents after leaving office, refused to give them up after multiple requests, continued to hide documents even after a search by the FBI.
4. Took Russia’s/Putin’s side in Helsinki, when asked whether he agreed with the unanimous assessment by the Intelligence Community that Russia interfered in the 2016 election; an assessment supported by his entire cabinet, and almost every member of Congress.

“My people came to me, [Director of National Intelligence] Dan Coats came to me and some others saying they think it’s Russia. I have President Putin, he just said it’s not Russia,” Trump said. “I will say this, I don’t see any reason why it would be.”

Moral

1. Is a convicted rapist.¹
2. Is a convicted felon, guilty of felony falsifying records based on evidence showing he was attempting to influence an election.
3. Appears on Epstein’s flight logs multiple times¹ and has praised him many times.^{1 2 3}
4. Stole from a children’s cancer charity, which led to a penalty of $2 million and dissolution of the Donald J. Trump Foundation which he established in 1988.
5. Mocked a disabled reporter in front of a crowd.^{1 2}
6. Said that he would have sex with his daughter if she wasn’t his daughter.^{1 2}
7. Bragged about sexually assaulting women.
8. Pardoned 3 war criminals.
9. When asked during the debate to condemn white supremacist groups, such as the Proud Boys, instead said “stand back and standby”. Bizarrely NOT condemning them, but rather appearing to signal to them to ‘cool off until given the signal’.
10. On day 1, Jan 20th 2017, bold-faced lied and kept insisting that he had the biggest inauguration crowd in history despite photo, video, and timelapse evidence to the contrary from Obama’s inauguration. Kept lying in the face of overwhelming evidence to the contrary, setting up a constant aggression against the truth. Recently lied that his January 6th crowd was bigger than MLK's "I have a dream" crowd.
11. Lied that millions of illegal immigrants voted illegally in the 2016 election despite producing zero evidence, nor finding any through the Commission he created tasked with finding the evidence. Kept lying about it throughout his term anyway.
12. When talking about powerful men sexually assaulting women throughout history said that “unfortunately or fortunately” that appears to be the case. Fortunately?

Legislative / Executive

1. SCOTUS: Alito and Thomas will be 75 and 77 on Jan 20, 2025. A 5-4 liberal court is possible! It would be the first time since 1971!
2. Roe v. Wade: Bragged about overturning Roe v. Wade,¹ and then lied that “everyone, even all the Democrats wanted the issue to return back to the states”.
3. Reproductive Rights: Has taken every position on abortion, but has continuously done the work of the evangelical right who have called for an absolute national abortion ban without exceptions. Other threats to reproductive rights include IVF restriction, morning after pill ban, birth control ban, contraception restriction, felonies for miscarriages, and death penalty for abortions. Pretends to be a moderate on abortion because of how extreme his and the GOP's plans are.
4. Economy: Gave away trillions of dollars to the ultra-wealthy and corporations with the Trump tax cuts. Allowed 17%, or $200 billion, of PPP and EIDL (Covid) loans to be stolen and unrecovered. The economy does better under Democratic presidents according to virtually every single metric.
5. Project 2025: Is closely associated with the director and creators of Project 2025, with many having served in Trump’s administration. Agenda 47 is closely similar to Project 2025. Trump supports both but tried to distance himself from Project 2025 when it went viral and the public recoiled at its extremism. Don’t believe his lies.
6. Israel/Gaza: Wants Israel to “finish the job” and "go and do what you have to do" as long as they don’t produce bad PR over it. "Go and do what you have to do. But you don't do that [showing videos of destroying buildings because it's bad PR.]". Netanyahu wants Trump to win.
7. Ukraine/NATO: Wants to pull funding for Ukraine and has threatened to pull out of NATO,¹ weakening both and thus bolstering Russia’s geopolitical strength, aggression, and opportunities. Advocates for Putin’s “peace” plan.
8. Climate Change: Has shown a gross disregard for climate change action and parroted climate change skepticism. Thinks wind turbines cause cancer. Cannot be trusted to enact or support legislation. He pulled out of the Paris Climate Accords. Giving him 4 more years to stall at this crucial period of warming is a literal existential crisis. We cannot allow Trump to contribute anymore to the so-called Great Filter of civilization.

Psychosocial

His animosity, lack of manners or decorum, obsession with bold-faced lies, and innumerable moral and legal transgressions has created a political atmosphere in which his supporters are heavily judged for supporting or defending such levels of beyond the pale behaviors. This creates hot-tempered discourse, social distancing, different universes of “facts”, and other problems that did not exist in any way to this degree before Trump. This slowly tears at the fabric of society by creating bad, worse, or no interactions between people because of his hold over his cult who will parrot his lies. Returning him to power will strengthen that division and weaken our country, society, communities, families, and our minds as we waste time on him.

He is extremely boring, stale, repetitive, predictable, and filled with childish meanness and immaturity. Having him centrally in the political conversation, as opposed to a bloviating carnival barker on the sidelines, is a collective brain rot for the country.
