Trump is a smart guy. I am certain he has poll tested everything he says. He has his people poll test the question “Should the parties work together”. He sees that a good majority exwants Kumbaya America so he runs with it. But since he has no core convictions he does not grasp that conservatives do not see how you can make deals with the people destroying the country.
We will see what happens in Iowa. A good test on how strong the Trump koolaid truly is.
I'm pretty sure he has NEVER poll tested anything he says.
