Part of what Trump ran on, was that he would undo Obama's legacy, so it's a good bet that he would go against anything Obama was for.
A combination of blacks, Asians and Hispanics voted for him, along with white voters, many of whom were neither poor, nor trash.
Our National Debt is in the trillions and rapidly growing. Our government, so in debt, borrowed from China and with continuing growth in the National Debt, it was evident that it would only get worse and we wouldn't be able to repay the loan. Because of policies like NAFTA, our US companies bailed out of the US to other nations to take advantage of cheap labor and no unions, thus giving Americans, cheaper products. That also meant a massive loss of jobs in the US. We became more of a consumer nation and less a producing nation. Add to this, many Americans still believe in having an actual sovereign nation with actual borders and a way to evaluate who comes in to the US, so as to reduce the entry of those who would seek to kill non-Muslims (like yourself, any children or grandchildren). There are also literally 80+ million (legal) firearms owners in the possession of approximately 350+ million firearms and many of them seeing a leftist candidate who was vehemently anti-gun, anti-borders, anti-border control, with a far-left policy that bordered on authoritarian principles. Those who spoke among the protesters and rioters, made it clear that they were against our Constitution and free-speech, unless it jived with their own concepts, thus an authoritarian stance that was clearly anti-US Constitution. So, those who voted for the Frump, wanted:
1. To maintain a sovereign nation.
2. Strong border control and vetting to ensure that those who enter, are neither criminals, nor terrorists.
3. Job growth which meant less restrictions on company growth.
4. To secure the right to own firearms for the protection of themselves, as well as their loved ones and also to keep them for sports and hunting.
5. Related to #2, many, seeing the global carnage being caused in the name of Islam (30,000+ Islamic attacks across the planet since 9/11) and 320,000,000 Muslims who readily admit that they are vehemently anti-non-Muslim and want us converted, subjugated or, killed) consider the freedom of religion portion of our Constitution to be our Achilles heel when it comes to Islam and want significant restrictions on them in place. Tokyo, Japan, is the largest city in the world, yet they have no Islamic terrorism; the reason being a small Muslim population with those being monitored, not to mention that conversion to Islam in Japan is considered culturally degrading.
