Trump made a lot of promises, as every person campaigning does. Now that he is going to be president, the reality sets in.
Obviously, many things he said are not going to happen, BUT a lot of them will start.
1) Building a wall. Since this is a process started in 2006, and 680 miles of it has been built, this will restart and and least in the populous areas, this wall will continue being built. In other places, drone technology, laser walls, and innovate processes will be researched and set up.
2) Obamacare. Everyone knows this is a disaster, but it has its good things too. The key it to find something in the middle ground. Repeal this crap, and bring something that will satisfy many of us. Two months ago, we received a 25.8% raise, which is fucked up. That needs to go.
3) Supreme Court Nominee - here is the biggest issue. Trump needs to put a moderate Republican candidate there, not a die hard one that will hurt all of us. I am not a right to life person, BUT having two kids, I agree that you need at least a 20 week or four month window before you cannot have an abortion (unless the mom is in danger). From experience, having that option is a necessity.
