Why is she voting at all? I will never understand these people. Don't get me wrong, I get the point you're trying to make. 3rd party candidates most always skew elections in favor of the Democrat. Perhaps not in your case, but it's true most everywhere else.
Neither Trump or Hillary are well liked, but one or the other is going to be the President. Wasting time voting for people like Ron Paul, Perot, Johnson, and the rest are a waste of time. Trump needs every vote he can possibly get. Even then, with the massive voter fraud the Democrats are famous for, I doubt he stands much, if any chance. If you doubt that, just look what Hillary and the Dems did to Sanders. Why wouldn't they do the exact same thing to Trump. With Democrats elections are won BEFORE election day. Sadly, this will be the case here as well.
