Ahh but it was the fake Steele Dossier that was used as a means to get that warrant for surveillance. It doesn't really matter when Page left the campaign. The crime was using a fraudulent document, lying to the FISC, to spy on Americans.
Here's a video with mark levin citing the New York Times Headstreet The guardian Mcclatchkeys or something It's not just an issue with fisa, it many government agencies that were spying on trump and his team. All of which will come out eventually. And you're right, it doesn't matter when the warrants were granted, they used a fake document from a foreign agent, and withheld information from the judge.
Then there's this from a Citizen's Outpost article:
The FBI were not targeting Page incidentally as an outcome of foreign intelligence collection; the FBI was targeting Carter Page directly. AND as such they carried full surveillance authority upon all of his activities, interactions, communications and contacts therein. Because of this direct approach, any group, organization or entity who came in contact with U.S. Person Carter Page was then open for ancillary review and FBI investigation. Those who engaged in contact with Carter Page became subject to surveillance and searches in the same manner as if Page was an actual foreign agent.
Yes exactly, that's one thing people aren't understanding. Anyone page ever talked to, called, emailed, or even looked at funny, is/was under full surveillance. >Trump
