What’s will happen if the president dies and Vice President dies, what person will take up the role now?

This answer depends on really where you live (This part is from Taiwan)

If the President dies, the Vice President takes over

If the Vice president dies, then they might simply just select a new President

Though that is very unlikely

I hope this helped. If it's wrong, blame me

Ps. Brainlistes would help a lot

Explanation:

this is a very nerve-wracking thought, as if we didn't have a president, most people think that America would be free for the taking. but in actuality, the president is mainly the guy in the chair that approves most large things that happen, like if America is about to go to war, he controls I'd we fire or hold our ground.

if the president were to die, the only thing that would happen is the control of America would go to the house of representatives.

and if they all were to die (highly unlikely) then it would keep going down the line to people of the highest power.
