Yes, and so did Yasser Arafat. what does that prove?
Just because some people don't "itentify themseleves as a liberals" doesn't mean they aren't. Indoctrination of newer gernerations from "our" education system, and the alphbet media conglomerates has changed the metrics/perception of what is deemed liberal on issues of import. The Portrayal of "middle of the road" is not what it once was.
The 2002 elections was a defeat for liberalism, and I hope is a sign the pendulum is swinging the other way.
