I guess in comparison to her husband it's easy to make the assumption that she was the better of the two, but that's not really accurate for the situation. Even from the limited time in the limelight she had, it was clear she really didn't give a quarter of a shit about doing her job.
The absolute joke of a campaign against cyberbullying, ignoring the elephant in the room on that being run by the First Lady of the current president, barely registered as a blip, with almost no significant reports of positive change due to it, and probably wasn't even committed to much further past the month it was announced. She was caught on tape last year saying less-than-favourable things about her task of organising Christmas decorations, though an extremely charitable person might say that was due to COVID and lack of enthusiasm for a typical Christmas in light of that, so maybe that was as much down to stress as it was about indifference. Maybe.
Beyond that? Er, well she wore that one coat about not caring while she visited the children in cages. And... That's really all I remember of her. I barely even remember hearing what she even sounds like when talking. Again, compared to Donald, doing very little at all is at least somewhat preferable to being an indescribably, relentlessly destructive monster. But compared to Michelle Obama's active, proactive duties, her powerful and charismatic personality and a clear sign of wholesome marital values with her husband? She's fucking Z-tier garbage.
