Why would any reasonable NY Dem primary Cuomo? He is a very successful incumbent w/ real achievements on his party side (did anyone say "gay marriage"?) - and he is not really hated, just, may be, slightly annoying to some. Even to mount a serious challenge would be extremely costly. And to do this merely to run a serious risk of electing a Republican in a race that should be safe Dem? What's, exactly, the point?
he is certainly hated by education unions and elements of the activist-progressive infrastructure. however they will not stand in his way.
