Once you’re in place and have access to tax dollars instead of campaign funds, you get them spent on things by putting that community infrastructure into place.
One problem with that is they’re running for a collective position. In their campaign, they’re captain of their own ship. A congresswoman is more a crewmate. Greater power, but more divided.
One thing they would be able to do, though, is never stop campaigning. They’ll be less active, as a congresswoman, but the campaign pivots to next election (which, let’s be honest, that’s already the norm, there is no break from politics anymore), and that next election can be focused on on-the-ground community campaigning the entire time.
So, no, you won’t see the same level of activism with tax dollars, they don’t lead, but she and others that follow her can do good consistently with their position through campaign funds and fight for good in their government while that happens.
The difference is, if this were to happen and it was found later that a court case crucial to the defense were used, that’s a mistrial. Maybe even dismissed with prejudice.
Courts are bullshit sometimes, it’s true, but it would take deliberate judge/lawyer collusion for this to occur, or the incompetence of the judge and the opposing lawyer.
Is that possible? Sure. But the question was “will fictional LLM case law enter the general knowledge?” and my answer is “in a functioning court, no.”
If the judge and a lawyer are colluding or if a judge and the opposing lawyer are both so grossly incompetent, then we are far beyond an improper LLM citation.
TL;DR As a general rule, you have to prove facts in court. When that stops being true, liars win, no AI needed.
