I don`t know if Donald Trump`s ever been to an actual polling place, but, you know, he doesn`t even worry if what he says is true. This is just about him worried that he`s losing.
The great misfortune of the modern English is not at all that they are more boastful than other people (they are not); it is that they are boastful about those particular things which nobody can boast of without losing them.
