He called them STUPID....
NO he didn’t - post the full quote in context.
How stupid are the people of Iowa? How stupid are the people of the country to believe this crap?
In this instance the context was Dr Carson's religious conversion (From Briebart. )
In his biography, Carson has written about finding God after one of his violent outbursts, and doing so while sitting alone for hours in a bathroom. Trump wasn't buying it, and appeared to attack as "fools" and "stupid" voters who have, specifically Iowa voters:
Anyone in Iowa or the whole damned country is stupid to believe a man who told of the night he found God. This is how he wins. It turns my stomach because Trump has no boundaries.
