He will help repeal Obamacare.
Put the proper perspective on what foreigners need to do to get lawful entry into the US. Currently, his protestors especially in New Mexico are flying the Mexican Flag, and Burning the American Flag. It shows that they only want to use the US to support their country, Mexico. They have no patriotism to the US.
Trump will give a needed new look at War, the Economy, and put a valid replacement in the SCOTUS.
He will give more transparency into the presidency.
He will focus on the middle class, and try to bring it back to life. The previous presidents either focused on the poor, or the rich.
Most politicians don't live in the same world as real people. Even though Trump is rich, he has been hit by the same bad economy as the rest of us. The politicians, as well as the federal employees live in denial of bad economies because the federal government can't go bankrupt. The federal employee retirement system is a Defined Benefits Retirement which means that no matter how bad the economy they will get the defined benefit. As opposed to 401ks where the economy in 2008 lost significant amounts of private retirement funds.
The world respects strength, and the US has been seen as vulnerable especially in the last 20 yrs. Trump will scare the bad guys because he is not a politician and they don't know how to deal with him. They know how to deal with the Clintons, and Obama as well as the Bushs.
Trump will also deal with the Income Tax System and make it more favorable to the middle class. Again, the poor people don't pay taxes. The rich people can hide much of their wealth by using the Internal Revenue Code. In 1986, the Tax Reform Act took away most of the deductions that could be used by the middle class.
In general, Trump as the unpolitician can better try to cross the aisle, or make the other side want to cross it.
