“A Catholic would be guilty of formal cooperation in evil, and so unworthy to present himself for holy Communion, if he were to deliberately vote for a candidate precisely because of the candidate's permissive stand on abortion and/or euthanasia. When a Catholic does not share a candidate's stand in favor of abortion and/or euthanasia, but votes for that candidate for other reasons, it is considered remote material cooperation, which can be permitted in the presence of proportionate reasons.”

Context: The masses demand a fighting President, and that means you’ve got to offend somebody, because the way I see it, a strong offense is the best attack.
So what can you offend?
That’s an easy one. Offend the other candidates, because they’ll be too busy talking to hear you, and besides, they might not vote for you anyway.

Context: A man offered to sell, and did sell, to Abraham and another as poor as himself, an old stock of goods, upon credit. They opened as merchants; and he says that was the store. Of course they did nothing but get deeper and deeper in debt. He was appointed postmaster at New Salem — the office being too insignificant to make his politics an objection. The store winked out. The surveyor of Sangamon offered to depute to Abraham that portion of his work which was within his part of the County. He accepted, procured a compass and chain, studied Flint https://books.google.com/books?id=iakIAAAAIAAJ and Gibson https://books.google.com/books?id=SIERLtc5aAYC a little, and went at it. This procured bread, and kept soul and body together. The election of 1834 came, and he was then elected to the legislature by the highest vote cast for any candidate. Major, then in full practice of the law, was also elected. During the canvass, in a private conversation, he encouraged Abraham to study law.<!--pp.18-19
