From a much longer list in the Washington Post
Build a wall along the southern border that's taller than the arenas where Trump holds his rallies, taller than any ladder and one foot taller than the Great Wall of China. This "artistically beautiful" wall will be constructed out of hardened concrete, rebar and steel, and it will be "the greatest wall that you've ever seen" -- so great that the nation will likely one day name it "The Trump Wall."
Make Mexico pay for the wall. If Mexico refuses, then the United States will impound all remittance payments taken from the wages of illegal immigrants, cut foreign aid, institute tariffs, cancel visas for Mexican business leaders and diplomats, and increase fees for visas, border-crossing cards and port use.
Get rid of Obamacare and replace it with something "terrific" that is "so much better, so much better, so much better."
Defund Planned Parenthood.
Temporarily ban most foreign Muslims from entering the United States "until our country's representatives can figure out what is going on." Trump would allow exceptions for dignitaries, business people, athletes and others who have "proven" themselves.
Heavily surveil mosques in the United States. Trump has said he's open to the idea of closing some mosques.
Never take a vacation while serving as president.
Prosecute Hillary Clinton for her use of a private e-mail server while serving as secretary of state.
Be unpredictable. "No one is going to touch us, because I'm so unpredictable."
"Bomb the s--- out of ISIS." Also bomb oil fields controlled by the Islamic State, then seize the oil and give the profits to military veterans who were wounded while fighting.
Target and kill the relatives of terrorists.
Bring back waterboarding, which the Obama administration considers torture. Trump has said he's willing to use interrogation techniques that go even further than waterboarding. Even if such tactics don't work, "they deserve it anyway, for what they're doing."
"I promise I will never be in a bicycle race. That I can tell you." (This promise is connected to criticism of Secretary of State John F. Kerry, who was injured while riding a bicycle amid the Iran negotiations.)
Rather than throw the Chinese president a state dinner, buy him "a McDonald's hamburger and say we've got to get down to work."
Force Nabisco to once again make Oreos in the United States. And bully Apple into making its "damn computers" and other products here.
