I think that's the correct interpretation of the data which you've presented. Who knows what they think about abortion. It's a stretch to extrapolate candidate preference to a positive choice in favor of abortion which is what your headline says.
I'm fairly certain that if you asked them, they'd say they were not pro-abortion but were looking at the "bigger picture"; i.e. Cardinal Bernardin's flawed "seamless garment" theology.
IOW, they're clueless.
In the election of 2012, Obama was the MOST pro-abortion, anti-Catholic candidate. Voting for the most pro-abortion candidate in an election is what I MEAN by the term “pro-abortion.”
I appreciate that you have offered a small ray of hope (if being “clueless” can offer hope!)to this dismal thread.
I am old, so you will have to excuse me for dating myself; but when I was young, many years ago, we called this kind of information “hanging our dirty linen out for the neighbors to see.”
I don’t say that we Catholics should ignore our problems. Far from it. I’ve done my share of confronting them in my lifetime.
But I do see a value in keeping a certain discretion and prudence in regard to opening it all up to those of an antagonistic or secular position.
