When the stock market is having fire sale is not the time to ask questions, it is time to buy. Trump is near 80 - he won’t be alive in a few years. He stastically has a 25% chance of not even finishing his term. Power will shift and shift again ever few years. those who stick to a good plan do fine.
Even in the worst case you are unlikely to find the better answer ahead of time. Just enjoy the sale and forget about daily movement.
Depends on unknowable factors like how old you will live to.
