From the comment section of the above article:
I just got off the phone with a friends wife who was in the Lutz group last night and she told me that the group was padded with Rubio supporters. She is a pro Trump supporter and almost none of her comments were televised. They were selective on the questions for the viewing audience.
Didn’t Luntz have a nice fat contract with Rubio a few years back? Of course!
Trump knows what he's talking about.
