I'm a current Columbia student, and will (hopefully) soon be Final Select for BDCP. I'm politically liberal, like many of the people working on returning NROTC to Columbia, and the perception of Columbia as monolithically crazy-left-wing, while true to a certain degree in the faculty, is much less true of the student body. I honestly don't understand the DADT-based opposition to NROTC; it's not as though the military made that policy (Congress did) and boycotting the military does nothing to change it. There are few enough militarily inclined students here (though quite a few in GS, which is an undergraduate college originally set up for GI Bill students returning from WW2) but I think Obama and the new Congress are likely to repeal DADT in any case, which will strip the facade away from the groups that hide their anti-military sentiment behind Don't Ask Don't Tell.
I think the fact that the opposition is basing its entire platform on that one issue will make it very likely that they'll crumble if DADT is repealed. So when ea6bflyr says "never gonna happen," I think, with due respect, that he might be wrong - I know several PLC students here, and several others who have expressed potential interest in service. Columbia is stupid to ban ROTC, but the Navy would be foolish not to put a program in place if allowed - there's a real untapped potential to put well-educated, if left-leaning, individuals into uniform.
