Whakakiia te rerenga e whai ake nei: I whakaingoatia a Dempster hei kaitono ki te
1956 Democratic National Convention i Chicago, ahakoa i tino reti ia i nga mahi torangapu o te taone nui i muri i tana hinganga i te tau 1955. I muri mai ka hoki mai ia ki tana hoariri tawhito a Cas Walker i roto i te ngana angitu ki te aukati i te whakakotahitanga o te taone nui, i tino paopaohia e Knoxville me Knox County kaipōti i roto i te pooti pooti 1959. I mate a Dempster i te mate ngakau i te Mahuru 18, 1964. Neke atu i te 1,000 nga tangata pouri, i roto i era ko nga senators o te US Al Gore, Sr., me Herbert S. Walters, i whakakiia ki te St. James Episcopal Church mo te tangihanga o Dempster. I tanumia ia i te taha o tana wahine i Greenwood Cemetery.
