As for Harris, I do not know when her passion for cryptocurrency started, hers looks more like a political ambition. She may never win against Trump. I will advise all US citizens to watch carefully.
They both have one ambition, and that is to be the president of the United States of America, every other thing is just secondary, and that includes BTC. I don't know who is going to win the election, but BTC users should not think that any of them would change so much for us in the BTC network, the U.S wouldn't suddenly start supporting BTC in its decentralized nature nor will they allow mixers and no-kyc services to operate without troubles.
