Not everyone in Maycomb loves Atticus Finch, but nearly everyone respects him. Perhaps no better example of this is how Atticus repeatedly runs unopposed for the local seat in the Alabama legislature. No one else in Maycomb even considers running against him. When Judge Taylor needs legal representation for Tom Robinson, he turns to Atticus. When Walter Cunningham needs an attorney, he chooses Atticus, knowing full well that he will not be able to pay him; and that's OK with Atticus, who accepts Cunningham's goods as trade. Miss Maudie understands that Atticus is a special man that the people of Maycomb have grown to respect and even use to their advantage.
"Whether Maycomb knows it or not, we're paying the highest tribute we can pay a man. We trust him to do right."
Be they black or white, rich or poor, Atticus treats everyone the same. His actions are not lost on his neighbors. After Tom is found guilty, his black supporters in the balcony stand in unison as tribute to the man they respect without question.
