The language was "Trump will be in prison by July 4th, 2022." There are a lot of steps between indictment and sentencing. Metaculus now predicts 9% that "Donald Trump is incarcerated for any period of time, no matter how brief, before June 30, 2028."
Yeah, if Trump taught me one thing, it's that any and all Trump-as-defendant lawsuits will be dragged out as long as possible. Jennifer Rubin got it right today, and I should have explicitly said in my post that this DoJ memo greatly helps any prosecutors trying to establish Trump's intent. Evidence like this makes it much more difficult to claim that Trump actually believes that the election was stolen, which would/will certainly be the crux of Trump's legal defense arguments. Even with all its glaring imperfections, I still believe we require a legal system. The courts have been the most credible way that Trump's false election-related claims have been rebuked thus far.
