I don't think so, they wore their religion as a merit badge and claimed to live by every letter of the law. This is why they constantly challenged Jesus with the law.
However, I can say they were the conservatives either since I don't think they live according to the law. They know about grace. If anything, Jesus would be the one with the liberal interpretation of scripture. Jesus continually said, "Yes, that is what the law says BUT etc..." If your animal feel in a whole or do you mean these men should starve to death...
Then again, Christianity isn't Judaism so I really don't call Jesus a liberal.
