Ginsburg is a liberal, but she is also a Jew.
Regardless of how liberal she is (and that is VERY liberal, wasn't she very high up in the ACLU?), she is also smart enough to see Obama for who he is -- a muslim who hates Jews and Israel.
She does not want to give him the ability to appoint her successor. Not only will that successor NOT be Jewish, but might very well be the first muslim appointed to the Court.
She is trying to wait him out, even "to the death".
Prediction:
If Obama is impeached and removed, and Biden rises to the presidency, watch Ginsburg resign soon afterwards, probably "for reasons of health"...
