For just the appeal I don't think anyone would need to rush anything to have it done before 2027, if it goes to cassation and beyond it probably would need to be rushed somehow for it to happen before 2027
If by recent years, you mean the last 20+ years, sure.
I'm not sure it truly hurts the Front National chances in 2027, however, the expected heir, Jordan Bardella, is not nearly as smart as MLP, so maybe it will make enough of a difference if it ends up a close thing. I would say the political situation in France is pretty volatile, hard to say what it will look like in 2 years.
There is also the possibility (slim, imho, but still real) of MLP either winning her appeal (which should take place sometime in 2026), or at least having the ineligibility sanction removed, which I think would give her a huge boost.
I don't know how it is in the USA, but here biologist graduates are mostly women, so I think the implication is that she was being called a biologist (who can't design experiments) because she's a woman
Authorities are investigating a possible link to drug trafficking, terrorism implies some sort of political revendication/objective which so far has not been the case
My personal experience is that I just translate one idiom from one language / culture to the other without realising and still expect ppl. to know what I mean.
That often works in my experience, and can lead to funny moments
Just imagine your mom saying your full name with an audible full stop, right after you said/did something a bit dumb
