Politicians cover the spectrum in their views. As has been said, sometimes it wouldn't matter as much for local officials who have little or no direct bearing on state and federal decisions. Sheriffs, county councilmen, school boards members, etc., may fall into this category.
Picking a person to vote for means you're picking between two sinners. This always means that we must tolerate something we disagree with, with nearly every person we meet, in order to maintain personal relationships. We often do this when deciding upon which local church to worship at. None are perfect, but there are generally acceptable options most everywhere.
One thing I always consider is the politicians world-view. Here is where I really have a problem with a pro-abortion candidate. While this is an issue of abortion, I think it's part of a whole-world-view of the candidate. How one views privacy issues, government intrusion issues, personal rights issues, etc., are all part of a whole belief system. Anybody pro-abortion is, in my opinion, beginning their world-view on a terrible foundation. This causes me to question nearly everything else about the individuals belief system.
While, in an extreme situation, vote for an openly pro-abortion candidate, it would take an extraordinary set of circumstances.
