Much of what our future will look like will depend, not the future President, but on who replaces Justice Scalia on the U. S. Supreme Court. Donald Trump would likely be less affected if a moderate or liberal judge was appointed to the Supreme Court than if the new Justice were a conservative. We could count on Trump to nominate justices who would reflect his philosophies which tend to be socially liberal.
In the case of Donald Trump, the future would also depend upon his getting help from experts in legislative management to get cooperation from Congress. Based on Trump using deception, anger and fear to coerce deals, his working relationships with Congress might well suffer. He might not be able to get much done. So, he might resort to many executive orders such as Obama has used.
In his funding of projects, Trump might find great difficulty in getting things done. This would be true of any President. But, in the case of Trump, because of his probable difficulty with relationships and lack of knowledge of legislative ways, it may be even more difficult to get Congressional approval of his programs.
In short, Donald Trump would find great difficulty in dealing with legislation. What he may excel at doing is making his business friends rich by inviting them into his administration.
The military under Trump, would be used largely for support of trade, not so much for political alliances. So, support for Israel would likely suffer. Deals with Iran would be fine if the trade were profitable.
The welfare and entitlements might stay much the same as long as funding would remain. However, Trump sees these as costs not as benefits. So, they would likely suffer.
Trump is not concerned about Constitutional matters. Relations between the federal and State governments might also suffer. However, Trump might allow States have more local control because he would not want to bother with them.
Moral ethics in government are already in a tragic condition. Under the pragmatic Trump, there would be no obvious reason for them to improve. Trump already has an unsavory reputation for disregard of morality in personal affairs. Christian values voters can expect no post election favors unless favors are given in exchange.
Donald Trump is great on appearances and promises, charm and charisma. He will not likely provide America with leadership resulting in the greater good for the people. We would be worse off after Trump became President.
