Someone got their claws into MTG to have her come out as a dark horse candidate aiming to disrupt a JD Vance presidency. She would be the candidate in this scenario. She is being positioned to be the candidate that “saw through the bullshit and is on normal conservatives’ side”.

It very likely will work.

It may work but it’s not likely to. Marj is/was too much of a whack-job and she’ll have a harder time becoming seemingly “sane” again. I hope you are wrong at any rate.
