Ron Paul can't win because he's not even actively campaigning.. I agree with you in sentiment, but Gary Johnson coming a strong 3rd will do more for the movement than voting for Ron Paul at this point.
And besides I think you are being disingenious to Gary.. He's been Libertarian for a LONG time and supported Ron Paul in 08 and showed his support even during this Republican primary. He doesn't share 100% of Ron Paul's take on libertarianism, but he's a darn sight closer than Romney or Obama ever will be and it might help people look into and join the Liberty movement. Which is whats going to help us all in the long run.
