On the issue of single issue voting, I had an interesting experience on election day. 

At a social after Mass, a woman who had never before spoken to me plopped down beside me, declaring in a loud voice, "I voted for LIFE. I voted Republican." Nonplused, I said, "Oh you don't like Democrats?" I'm not a Repub. or a Dem., but I voted for LIFE." Oh, I get it, you're a one-issue voter." (Mea culpa, by  that time I was egging her on). "No I'm not. I can't stand Obamacare. My premium went up to $700 a month." "I love Obama," said I.  Someone else at the table suggested she go online to find something cheaper. "I don't have time for that s..t!" she shouted and flounced out cursing loudly like a sailor. 

Don't really know where all that came from, though I have a suspicion of someone who might have put a bug in her ear about my political leanings. But my point in telling the story is that some who want to vote their wallet may be using the abortion kerfluffle to salve their conscience.
