Presidential election years typically have a 55-60% turnout, while midterms are closer to a 40% turnout on the high end. Mayoral elections, as noted, haven't had a turnout this high since 2001.

To suggest that the pool of active voters out of eligible for a presidential election is the same active voters for a mayoral election would also not be correct, its a different portion of the voting base that turned out. As I mentioned before, some areas (notably areas with a large POC population) had a substantialy different turnout.

The liberals who vote in presidential and midterms then dont show up for a mayoral election remained largely unchanged.

The increase in turnout was from eligible voters who are not active (apathetic), who were instead motivated to vote.

So no, liberals did not get Mamdani elected. They mostly voted for Cuomo. In about the same numbers as other mayoral elections.

Its important to look at like-to-like.

Anyway, seems I'm not learning anything new here and I've got dinner to get ready, so enjoy your day. I'll be moseying along now.
