Barron is just a kid, doesn't know better. Eric, Don and Ivanka well they do.
I have nothing against Trump's children. They didn't run for president, nor didn't say racist comments etc.
Why condemn them because they have Trump blood. And if they did vote for their father, it's because it's their father. And you know Trump, he only cares about himself and his children. So he probably gave them a lot of support.
