I can 100% guarantee that God is going to ignore all of those prayers for 2 reasons:
1. This country is being cursed by God on account of it rejecting His commandments and laws. Look no further than the facts that America ran away from the Taliban with its tail between its legs(Lev. 26:19) and that some cities are flooded by hurricanes while other cities are experiencing severe heat and drought(Amo. 4:7).
2. The Bible teaches in both Testaments that God only listens to the prayers of people who keep His commandments:
"One who turns away his ear from hearing the law, even his prayer is an abomination." - Pro. 28:9
"And whatever we ask we receive from Him, because we keep His commandments and do those things that are pleasing in His sight." - 1 Jhn 3:22
Since Trump supporters don't keep God's commandments and believe in false ideas of God like Trump does, their prayers are a waste of breath. While this makes Trump look good in front of his supporters, it does nothing to help the country realize that it is still speeding towards national destruction. God is not impressed with Trump's shallow theatrics at all.
