Yes. The Humane Party platform calls for abolishing the property status of all animals throughout the United States of America. The HP developed the Abolition Amendment, a proposed amendment to the U.S. Constitution, for this very reason and created Aboliton Day (December 6) to promote abolition.
Here is the relevant excerpt from the Humane Party platform (2014 edition):
RESOLVED that appropriate legislation be enacted and appropriate governmental action taken so as to:
end inhumane, scientifically indefensible, and economically unsound exploitation of other species by humans, such legislation and action including but not limited to:
- elimination of both domestic and foreign trade in sentient beings, regardless of species;
- elimination of torture, mutilation, and slaughter of such beings;
- elimination of both domestic and foreign trade in products resulting from or obtained by way of such exploitation, such products including dead body parts of animals and live animal secretions; and
- elimination of services that include or are provided by way of such exploitation, such services including experiments performed on live animals and entertainment events that include live animals.
abolish the property status of (“emancipate”) other animals by either:
- explicitly recognizing all other animals as fully protected individuals under the 13th Amendment prohibition of slavery; or
- ratifying a new Constitutional amendment emancipating all other animals.
