Why was george h. w. bush criticized by many blacks, and by jesse jackson, during his election campaign in 1988?

He was criticized because of his position on African-Americans that was often racist. There were even racist ads about an African-American felon who raped a white woman in a state that was run by Bush's democratic opponent, and the goal of the add was to vote for Bush who could somehow stop things like that. He was criticized because of that kind of racist behavior.
