Being pro choice, pro gay, anti gun, to list a few, and I personally won't overlook any of those things! I know adultery is a "personal" problem but it's one that I won't overlook, because it's a reflection on his character. They are all deal breakers to me.
Save for vote for a *pure* candidate, by all means.
That's why conservatives lose elections. A certain segment has a laundry list of "deal breakers" and unless the eventual nominee passes the "deal breaker" test, they'll stay at home or cast some pathetic protest vote.
Instead of getting 90% of the pie, or even a third of a pie, they'll get 0% of the pie and think they've done a good thing for the country.
It's madness, but it's getting routine.
