“Why are Conservatives asking Perry to quit? I don’t hear any clamor for Ron Paul to quit.”
Ron Paul is in the race for two reasons, to promote libertarianism and to be a spoiler. He never actually planned to win and so any attempts to get him to quit will never work.
Rick Perry on the other hand, entered to win and so given he has almost zero shot, he should just quit.
Why should he quit? His percentage won’t make a bit of difference to Newt or Santorum. Go after either Newt or Santorum to quit if you want to make the arguement that Romney will win unless they do. Perry isn’t sucking oxygen out of anyone’s campaign and he has a lot to say.
