Granted, there are no direct sources for what de Blasio might do, but after what he did to NYC I can't see him winning anything ever again. All a New Yorker has to do is look at NYC and say 'do I want that to happen in my town?' The answer will almost certainly be no.
Ideally, he primaries Cuomo and damages him enough in the process to allow a moderate Republican to win.
De Blasio is serious about ‘longshot’ run against Gov. Cuomo, insiders say Talk about the blind campaigning against the infirm!!!
