Donald Trump has been on a streak of stupid, prejudiced comments on foreign issues and he has been on an effort to pass another version of Trump care that's even worse than the one that already failed in the Senate.
As it turns out, the whole thing is a mere ploy to try to boost his approval numbers among the most racists in his followers. Which is most of his followers.
How do we know that? Because Trump is actually paying for ads on Facebook aimed at the worst of the worst of his followers, trying to sell them the idea that he will build a border wall, when in fact he won't, as he does not have the numbers in Congress to approve the money to built it.
