I think the two people that you're looking for have left this thread. I can't imagine that there were very many people on this website who were more vocally opposed to Romney than I was in 2012.
Here's my only point. I agree the logic that leads people to stay home and not vote when we inevitably nominate someone like Romney. Personally, I wouldn't go that far, but I can empathize.
My observations are concerned with the primaries. Before I worry about who the absolute best, most conservative candidate is in the field, my first priority is to ensure we don't get stuck with a choice between Hillary Clinton and Jeb Bush or Mitt Romeny.
If all you can do is "empathize", then you're part of the reason the GOP has continuously slid leftward since Nixon's time. You enable them every time you give your precious vote to one of their hand picked quislings.
And don't start with, 'Well, that's better than electing a Democrat!"
That's demonstrably untrue, given the performance record of so many GOP-e office holders. As has been said thousands of times on this forum, there's not a dime's worth of difference between the two wings of the Uniparty. They're liberal statists, one and all.
I'll say it again: You Get More Of What You Vote For.
Vote RINO, and be assured that the GOP will give you more RINOs to vote for. If you want conservatives in office, then dammit, vote CONSERVATIVE ONLY.
