Have politicians who get elected mean what they say and do the promises they make to the people of the United states

Many politicians say things they don't mean and make promises they can't and wont even bother keeping, I'd like to meet and see one that means what they say, gets closer to the people and actually care for the average day American, after all like it or not we are all equal and at one point of time the people in power where once an average day american, I don't like how during promotions for themselves they slander and criticize others either, stick to yourself and mean what you say, your principles and what makes you who you are, they are what got you elected in the first place right? Why change just cause u have power now, it doesn't mean you should abuse it, stand talk and keep you values true to yourself and never forget "for the people, by the people"
