DJT's use of Twitter in 2016 allowed him to operate within his opponents' OODA loops.

DJT and his supporters could craft narratives directly, rather than going through traditional media.

DJT's information flow: DJT -> Twitter-based Supporters -> News Orgs -> Electorate

Other Candidate's info flows: Candidate -> News Orgs -> Electorate

So not only could DJT move faster, but he also didn't need permission/buy-in from Editors/Owners of news orgs.
