Children are today growing up in a world where a one-time beauty pageant runner whose name was largely synonymous with cartoonish wealth is now a serious contender to be the next U.S. president.

What happens when you put grade-school aged children in front of a string of Donald Trump's speeches and debate performances? According to a Fine Brothers Entertainment video, the kids discover Trump isn't much more mature than they are -- or in some cases less so.
