Rubio grinning while that woman was screeching was a horrible train wreck must see tv moment. It is a huge turn off for average viewers. Average viewers are not sitting in a Luntz focus group to air on live tv by the way. ;)
I haven’t watched the follow-up shows, but in the early part of the debate there was a woman screeching in the audience every time Rubio hit Trump. That was all she cared about. I was trying to keep myself from praying that she would lose her voice, and she did stop finally. That happened to me one time when I was singing Christmas carols.
