First of all, Fox News was caught off guard in Tampa with the Q signs and didn't keep the cameras on them for any serious amount of time no matter what anyone says.
Second, I'd be willing to bet Fox News was told by Murdoch management to keep cameras off any Q stuff in PA.
Third, I'd be willing to bet the real culprit in PA was GOP Establishment trying to distance candidates from Q by blocking access or use of any signs other than MAGA for tonight's event.
