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?
Those were all the great things he did.
He was right about the Hussein regime spying on him and his staff.
People protesting the stupid removal of statues are fine people.
Making fun of Kim Boi King is a good thing, because speaking the truth about tyrants is always a good thing.
He is leading America, and many in the free world are following suit. Much of Europe is now ditching the open borders policy and embracing strict immigration policies.
Withdrawing from the Paris accords was the right thing to do. We don’t need to submit ourselves to such accords in order to keep our emissions down. Our NOx emmisons for example are far better than Europe, as they continue to use diesel and make more and more people sick.
Calling out un-American shitheads is always a good thing. Protest what ever you want, but disrespect our flag and national anthem and it will backfire.
The travel ban was a huge step in the right direction. A true Muslim ban would be even better.
There is no redistribution of wealth to billionaires. The bottom feeders don’t pay any taxes, yet they take welfare, funded by billionaires.
What is wrong with golf? President Trump gets more done for this country in one round of golf than the Hussein did in four years.
He was elected on the idea of trying to make peace with Russia, instead of trying to start a world war with them like Hillary and the Hussein wanted.
He had every right to attack the shithead Muslim that attacked him on national TV while at the DNC. The lying “gold star” Muslim lied about what is in the Constitution, Trump had every right to put the piece of shit in his place, and that he did.
