I don’t know if Maryknollers would be so blatant about abortion. Unfortunately we humans can justify anything to ourselves, so that’s how some Catholics are ignoring Obama’s support for abortion by focusing on his Social Justice ideas about the poor, the War, health insurance for all, etc. They DO know, without doubt, that killing any unborn child is NOT acceptable to the Magisterium, and it is not acceptable to God.
I guess I’m answering my own question in #3644 but there are Catholics who always vote Dem no matter what. A lot of my mother’s relatives are an example of that, despite the fact that many of them are as conservative as I am. It makes no sense.
