I'm not asserting that the polling is wrong, but I would say that for many people polled it could be misunderstood.
From a Biblical worldview, God can influence leaders. Both who is put into office, and to some extent even change their hearts about situations to control their impacts in the world.
That is to say God can, not that every leader is chosen by God and even less so that every leader is approved by God. Many times God is shown allowing bad leaders as a judgement of the people.
So even among those polled who said they believe he was appointed by God, it doesn't mean all of them thought it was a positive endorsement. I think if God chose him, it's because he's the leader we deserve.
