Viewers should note that Usual Tard is using the official dem talking point script that he has been given.
The official lefty argument is that the fact that the fbi was watching Page before the dossier was developed and used to get the FISA warrant "proves" that the dossier is not what launched the FBI warrant.
No, it is the other way around, it proves that the FBI had been watching Page for three years but could not find enough on him to get a warrant, maybe even had one rejected by the FISA court, so then they used the dossier as a kicker to get a warrant.
Remember, McCabe told the Committee that "there would not have been a fisa warrant without the dossier."
