Another Smear word created by the Far Right to demonize liberals. In the case of this baseless term, it is used to describe liberals as being hypicritical without looking at all the facts. If one was to dig deeper they would find that Liberals would jump at the chance to use a less polluting form of travel.
Since this a term created by Rush Limbaugh not all the facts where considered.

Before you use a term like Lear Jet Liberal why don't you research all the facts and not make assumptions. Even though many Big politcal and enviromental advicates used private jets they would be the first to use a jet that did not use up so much fuel. The manufactures would make mopre fuel effishent jets.
