Re: Democrats and abortion
Surely your sister (and you) would not desert Obama or Clinton, uncompromisingly pro-choice both, if either proposed an abortion reduction program along the lines I have suggested?
Of course you won't get the hard-core anti-abortion folk, and yes, they are mostly anti-contraception. (I noted with horror that Peter Wehner's idea of an abortion-reduction program was "abstinence education"- does he expect low income people to be celibate their entire lives? Sheesh!) However, I am sure, knowing many moderate pro-lifers, especially my fellow Catholics, that many of them can be "peeled off" from the Republican party by offering them a non-coercive abortion reduction program.
As for the Catholic church being officially anti-contraception, that's true, but that teaching has been overwhelmingly rejected by US Catholics. My admittedly unscientific sample is that about 90% of US Catholics use contraceptives.
