Good point about all Jews being entitled to Israeli citizenship at birth. But the “Ted Cruz is Ineligible” crowd would say that Lieberman would not be ineligible, since he was born in 1942, 6 years before Israel became a sovereign nation. But as for Jewish-Americans born after 1948, watch out, the NBC Redefiners will be out to get you.
Oh yes yet another wrinkle I neglected to address, the dual citizen thing.
Some people seem to believe that ANY dual citizen is not eligible. Sorry folks, foreign law = irrelevant.
