Gawd, there are so many. I can't pick a single one. But I can name a few I think qualifies:
Lied about a former president saying Obama bugged Trump's phone. Then never apologized.
Referring to Nazi's: "some are very fine people".
Called an unstable North Korean leader names like Rocket man, short and fat.
Walked away from the Leadership position of the Free World.
Withdrew from the Paris Climate Accords.
Attacked an unemployed NFL player for having to nerve to protest the shooting of unarmed and innocent blacks.
Attacked an unemployed NFL player NEARLY A YEAR after he began to protest the shooting of unarmed and innocent blacks to change the subject.
The Muslim Ban.
Being able to say "Muslim Terrorists" but not "White Supremacist Terrorists", not even after murder.
Massive redistribution of wealth to Billionaires
Golf for a third of the year
His love for Russia
Walking around Mar a Lago willing to talk to anyone who pays membership fees.
The mistreatment of Gold Star Families.

I know most Republicans won't see anything wrong here, but the rest of the world has a different opinion.
Which is the worse and if I missed it, what was it?
Notice, when you post all the awful things Trump did during the year, no one says it's not true. Instead, they participate in a lame attempt at mocking what they imagine that someone is crying.
But who suffers the most? Trump's own voters.
Well, I just want Trump voters to know. When he fuks you over, I don't cry. When you lose your healthcare? I don't cry. It doesn't even occur to me.
So you shouldn't cry either. Isn't that why you voted for him?
