Time for some testimonials! 
A testimonial is basically when a famous person backs up the credibility of the politician, and endorses him or her with a add or statement. 

In these two adds, Shaq is telling citizens that Chris Christie is the one to vote for, he is good for New Jersey. 

“I don’t endorse many politicians. But Chris Christie is different.  He is working with me to bring jobs back to our cities and on a new program to help kids in tough neighborhoods to get ahead. Governor Christie’s provided more funding for schools, given parents more choices in what schools their kids can go to, and merit pay for good teachers.” In the other add, Kerry Washington (actress) hosted a event in honor of candidate Barbara Buono. When celebrities endorse a politician, people notice and so does the press.
