We are not talking about him because he is personally wealthy/his father left him lots of money. We are talking about him because in a few days time he will be president of the wealthiest and most powerful nation on earth, a job that he has managed to secure by convincing the majority of US voters.
And a vital component to his success is that he could not care less if people, who are never going to vote for him under any circumstances anyway, totally hate him. He has his target audience and that is all that counts to him. Actually being hated by lefties/liberals probably does him more good than harm.
In fact Trump goes even further than that and sometimes doesn’t even care if people who are likely to vote for him also hate him. A good example of that is when Trump stood in front of a Jewish audience and told them that he didn’t like them because they were not very nice money grabbers but that they would have no choice but to vote for him because the Democrat alternative would be worse for them.
He has a similar attitude towards evangelical Christians. He knows that he has absolutely nothing in common with them and they are under no illusions about him. But the deal is that they will vote for him because it keeps the Democrats out of power.
It all works very well for Trump. The interesting thing will be whether not being able to stand for a third term will affect how he performs/behaves during his second term.
