Actually if I remember correctly Harris will not take over Biden if C”V he wins the presidency. Due to Harris parents from different countries (although she might be american) she cannot become the president of the United States so instead it would C”V go to the speaker of the house and that would be even worse that would mean Pelosi would become the president of the United States C”V
I think it’s time for all of us to daven seriously to Hashem that this doesn’t happen or then we will all have to leave the USA immediately and make Aliya to Israel ASAP for there will be no other choice.
