The "Horton Hears a Who" book is one of the all time favorites of Delegate Kump, because of the lesson it teaches about the worth of every individual.
His favorite quote from the book is, "Don't give up! I believe in you all! A person's a person, no matter how small!...If you make yourselves heard! So come on, now, and TRY! ...We've got to make noises in greater amounts! So, open your mouth, ...! For every voice counts!"
