Yeah, far be it from me to rush to the defense of religion, but this is not quite as scary as it sounds. You could very well have a religious person answering this survey who absolutely hates Trump and thinks he is a force for evil. Like you said, most Christians believe literally every event is part of God's plan (which is quite reasonable given their axioms tbh).

In fact the article clarifies this:

"That survey, of a nationally representative sample of 8,937 Americans from across the U.S., found that overall, 4 percent believed God chose Trump because He believes in his policies, while another 32 percent think Trump’s election is part of God’s plan, although God may not necessarily agree with his program. Nearly half, 49 percent, said God doesn’t get involved in elections, while 14 percent said they don’t believe in God.

When it comes to white evangelicals, those numbers are much higher, with 8 percent believing God ordained Trump because He agrees with his policies, and 63 percent thinking his election is part of God’s plan, whether the deity agrees with his policies or not. Their beliefs held firm with regards to Joe Biden’s election in 2020 with 67 percent of white evangelicals believing his victory was part of God’s plan – but with the stark difference that a negligible percentage believed that God agreed with his policies."
