What exactly do you need help with? Converting it into a poem or knowing how... I don't really know how to help so sorry but if you explain a little more, I can (also don't have enough time to read the whole thing)

He was not nominated as President for the next term because he had turned against the spoils politics of the time and had supported Civil Service reform while he was President.<span>
