Answer:
To fix the country's problems with the economy and foreign possible threats he pardoned Nixon. He wasted a lot of time fixing the problems about Nixon so he saw that if he pardoned him he would be able to continue to solve the real problems that affected the whole country. This was a very unpopular move on the average voter and he lost the election.
You could say that he appealed to pathos. It's an appeal to emotion while ethos is to credibility. He used pathos to speak about sad things like secession and about the evils of slavery and why it should end. He didn't have to appeal to credibility because he was already the president so everyone knew why he was competent.
