The LP needs to continue its advertising since if RP doesn't get the nomination and drops out the LP is our only hope for liberty. Besides, the LP is not in charge of George and he should be able to do what he wants.
I don't care if they promote him, but when they take deliberate stabs at Ron Paul like this, that ticks me off. He has a right to freedom of speech, but the LP can still put pressure on him to tone down the anti-Ron Paul rhetoric.
