Statehood for whom? Are you referring to that hearing about NYC’s statehood recently? That was purely an intellectual exercise (and a bit of a complaint to Pataki), not a serious contemplation of statehood.
What identity has this place got? The only positive trait that comes to mind is proximity to the City.
Long Island wasn’t turned down for this metro status (and I cannot discern who/what was behind its motivation, what ‘they’ thought it would mean or what it ever meant or what it will mean.)
I posted to those threads for academic purposes only. I could boil my own feeling as ‘one citizen, one vote’ and LI with its geographical (though mostly Democrat) neighbours in Queens and Brooklyn would be the 14th largest state.
I don’t know the criteria of identity that LI had to get in years ago, nor what criteria pushed LI out.
