It actually started in the first debate with the first question. It was something about Trump being the perceived leader in the polls.
I thought at the time it was an inappropriate question because Trump was not be present to respond.
Later, there was a question that referenced Kasich, and I was of the same opinion — Kasich was not there to respond.
Then, at the 2nd debate, the first question was the ‘show your hands if you are going to consider running as a 3rd party loser’.
IIRC, I labeled FoxNews as ‘despicable’ in the early debate live thread.
I did not watch the first debate.
Apparently, the hit job started with the first debate and continued on
thru every part of Faux News programming.
