If i were god, Sanders would stay alive till he gets at least four full years of presidency

You are implying something right here, that God is the one who determines who rises to power, and who falls. Since America has rejected God, he is letting her fall. No one can save her, because she forgot where her blessings came from. She fell asleep and is dreaming. (Same for many of the Chinese.) America thinks she has no need of Him, that a man can save her. It's time for God to shake people awake, and it will be a rude awakening for most. I thank God he woke me up years ago, so I am awake and watching, trying to help others. God is saving individuals now, not the nation, and salvation comes only through Jesus, acknowledging his death on the cross to give us victory over sin and death.
