They're already linked. This is more the why's and hows. Short version. Think Robert Mercer, Cambridge Analytica, Bannon, et al. Russia could get routine polling data, even some deeper 'internals' (details about us) off the net. This is DEEPER shit, demographics, likes dislikes, media habits, zip codes, FB names. I'm betting this is the FB shit that Cambridge 'stole' and then merged it with TRUMP's internal campaign data. Remember Cambridge told FB it was gathering (OUR) information for "educational" purposes. FB FUCKED UP
ROYALLY!
