Of course abortion is a serious issue, but no where does it say that all the other items on the list are not to be considered after abortion has been considered. The statement from the Bishops gave a list of issues important to consider in that article, and it didn’t by any means stop with abortion. The Bishops want us to look at all of the issues and vote accordingly.
For example, if the only pro-life candidate is promising to wage war on N. Korea during his/her term, I certainly would vote to make sure he/she didn’t win the election. For example, If the only pro-life candidate is promising to outlaw firearms, I’d certainly vote to make sure he didn’t win that election. For example, if the only pro-life candidate is promising to double the taxes on farms, I’d most certainly make sure I vote against him/her. Just because the there is a “pro-life” candidate doesn’t mean that candidate is going to save the world. In fact, he might make it much worse. Vote the way your conscience dictates, and so will I.
