Cuomo looks like Dino from Flintstones in that
Is that why the DailyKos crowd calls him "DINO"?
No, they probably call him that because there's a thought of "gay marriage would've happened in NY anyway so we don't have to give him any credit there...and what gun control bill?" over at DailyKos
Also his shenanigans with supporting Republicans in the state senate, his support of fracking, his union-busting, his refusal to increase taxes on the rich (instead cutting services), his past as housing secretary (and the ensuing subprime loan craziness) and secretive demeanor.
