sorry 15,000 citizens, he needed a running mate. correct, Neither Trump nor Biden needs to known that yet. do what we say, not what we do
The rules are you either need to be selected(along with a running mate) by a party, or run as an independent with a running mate selected. trump and Biden have gone the selected by party route, and Kennedy is running as an independent. Kennedy did try to get selected by a party, but decided he would not be successful.
