Trump got his feelings hurt and so he’s going after Pelosi with these doctored videos. She has already been demonized many times so I don’t know how this really works, but it gives something for conservatives to entertain themselves and for the NYT to both sides this stuff.
The larger point is that these tit for tat games with no specific goal or target in mind tends to play to Trump’s advantage over time. The thing that Pelosi is pointing out is that Trump is engaged in a cover up and he is unfit. Those are great themes to sell and push. But there’s no follow up to say, ‘therefore, we’re going to hold McGahn and Barr in contempt’. When she had these spats with Trump during the shutdown, she had a larger purpose: ‘support federal workers’ and ‘no wall’. You will never hit as hard as Trump does when it comes to caricatures. But you can render him impotent and weak by proving that his positions are wrong for the country and that he lacks the temperament to be trusted on anything he says. You can also take firm positions that you’re willing to invest political capital in and win the support of your base + Dem leaning Indies.
