That's a good question. General McInerney on Steve Bannon's War Room (at the 1 hr. 23 min. mark) provides a clue to what happened. General McInerney states that The Hammer was a compartmentalized AI surveillance 'tool' and a government owned program. After Obama was elected Obama had it moved (stole it) and set it up elsewhere. They then modified it and made it more 'robust' and included "Scorecard" for political purposes. It is being used to flip the vote. Since 2016, they have made it even more robust and General McInerney says it makes it difficult to take out. Did Trump know where it was located? There are over 5000 outlets/servers, but Trump needs to take it down.  General McInerney says that The Hammer 'failed' in the 2016 election and Trump got elected. My 'Spidey Senses' tell me that there's more to this than a 'failing'. I believe White Hats in 2016 made it appear as if the vote had flipped, but it really didn't. Nevertheless, we all know the rest of the story as far as the election went.
