Firstly, Trump is widely known for his business expertise. Why, he has negotiated out of not 1, nor 2, but 4 different multi-million dollar debts that actually ended in his favor. What he would do was have the company file for Chapter 11 bankruptcy (in which the business can still operate), essentially ditch the whole operation, and then come back later when most of the debt has been dealt with by the banks to buy it back up. He has even admitted to "playing with bankruptcy laws", claiming "they're very good for" eliminating unwanted debt (Newsweek 2011). Just imagine how that can translate to his career in office: no longer do the American people need to worry about its national deficit, for the famous (and infamous) businessman can simply outsource control of the country until it's low enough for us to take it back.
Another attribute Donald Trump has is his experience in politics. Believe it or not, this isn't Trump's first attempt at running, as he originally ran for office in 2000 with affiliation to the Reform Party. Obviously, that brings into question his allegiance to the Republican ideologies he so vehemently pushes for this time around, but it matters little to him; in fact, he has had affiliation with both the Independent and Democratic Parties as well. The key factor he looks for in political parties, in my opinion, is whether there are people with shallow pockets looking to make them deeper. His standings on political issues change with every new criticism that arises, as is his attempt to 'please the masses', so to speak. This would translate much better once he attains the reigns of this country, as his flip-floppiness would keep us out of countless foreign troubles that would surely envelope America otherwise.
Now I know that there is mounting evidence against Donald Trump being a good person (i.e. him being a racist, sexist, power-hungry, egotistical old man), but let's choose to ignore those attributes. Instead, let's look at how well a businessman could run a country that's becoming as unstable as his toupee.
