Undermining the legitimacy of the new President to try to diminish his power seems common lately, e.g.: - Clinton only won because Ross Perot siphoned votes away. - Bush didn't win, the Supreme Court handed him the Presidency. - Obama isn't American. - Trump was only elected thanks to Russian interference. - Biden didn't win, the election was stolen. It's a tactic that gets used because it seems to work, at least in terms of rallying one's own troops.
