He knows that when he speaks on Trump State Teevee, he is talking to a zombie army of reprogrammable meatbags who will “remember” the past exactly as Gingrich — who is an authorized representative of the Republican Ministry of Truth — tells them to remember it. Until the newly revised “past” becomes inconvenient, at which point it will be re-revised, and the meatbags will “remember” the new version of the past just as fervently as they “remembered” the now-forgotten, previous version of history.
For example, now that the House of Representatives has changed hands and Democrats have the authority to launch investigations with actual teeth, the Party of Benghaaaaazi is suddenly “remembering” that congressional investigations are a terrible idea.
