What's Wrong with a liberal being Right?

This question, in one form or another, has long been one I've thought about, but particularly of late has the question arisen very often. Stated another way it might be asked "is a liberal ever right, for the right reasons?" I acknowledge that liberals are sometimes on the right side of a question, but again, is this ever for the right reasons? It seems to me that people can be on the wrong side of a question for the right reasons, as well as being on the right side of a question for the wrong reasons. Some people are on the right side of a question for the right reasons. But is this latter possible with a liberal?...
