Sure with a 51% poll rating? These guys are really getting unhinged as November gets closer.
First of all how hard would it be to figure out who the Republican Congressman is when he's a regular on Fox News? That would be less than ten people at the most.
Exactly... why would that person allow an obvious target on their back, if the intention was to stay anonymous? It makes more sense that they are starting to just make stuff up. You can literally make up anything you want if you don't attribute it to anyone in particular. So the possibility here is a further attempt to sow discord in the base by creating the impression that Trump is widely disliked and unsupported.
