I do not believe for a second Trump was trying to find out what THEY want, I believe it was a chance for them to get to know him on a personal level nothing more take him or leave him that is Trumps motto!!! Leave him and take Hillary!!!
Well, that makes sense.
He needs to get to know bible belt "Evangelicals" that are ALREADY safely Republican and a lock to vote against Hillary anyway, regardless of who the Republican nominee is.
But he doesn't need to "reach out" to the OTHER 75% of Christians in America, especially those living in swing state areas like the Midwest and rocky mountain states that are essential to win in November. You know, like the kind of voters the last Republican to actually WIN the presidency was successful in bringing into his camp.
Interesting "strategy" for "victory".
