Yes, its still possible, and I also wonder why NYC doesn't have a big nonpartisan primary, and then a top 2 runoff instead of a partisan general election like other cities do.
Bloomberg pushed for nonpartisan primaries, there was an attempt to revise the charter to allow it, but it didn't go anywhere. Neither party is really for it, since it would reduce a lot of their control, especially over judgeships. It's a good idea but it will never happen.
I could see Eric Adams winning in 2025 with a different ballot line if he lost the primary, honestly. But i think he'll probably win re-election.
Do you think he'll be challenged at all in the Democratic primary? I didn't realize that it was so close in the ranked choice rounds from 2021:

I don't know where his current approval stands, but I heard that he's receiving bad marks for handling the flooding last week... All I know about him is that he was a policeman and and he was favored much more than Bill DeBlasio, who left office very unpopular.
Apparently there's a coalition to find a primary challenger for him, led by progressive activist Allen Roskoff. So he'll likely have an opponent, but a serious one? Dunno. He has a coalition that will be hard to beat.
