There are several obvious irregularities in this election. There is very clearly some vote fraud. I'm don't how much, and I am even less sure if it can be proven in court. There is also denial coming from many people on the left when they say that there is no vote fraud. Some experts have said that mathematically some of this is fishy. This is not just something Trump pulled out of his ass.
Although Trump is narcissistic, he gives the strong impression that he means well. I believe that he does. He believes in his agenda. We voted less for the man, who like most people is flawed, than we did his agenda.
