[Mrs. Don-o]

"...you only commit a mortal sin if you directly assist someone in getting an abortion or if you yourself have an abortion."

Not quite. See #131.

[DaGman]

Yes, quite. #131 is worded nicely but is an interpretation or opinion.

Nor does #131 address the fact that, according to the Church, one can vote for a choice candidate as long as he/she has done thoughtful introspect into the moral reasons for voting as he/she chooses and has a clear conscience in doing so. For example, if someone votes for a pro-choice candidate because they feel he/she will do more to better economic conditions which are directly related to the rate of abortion, then, they can justifiably have a clear conscience on the matter.
