Gary through his own words has proven he doesn't know enough about the FED or economics.
Gary knows the three words that are all anyone needs to know about The Fed: "End the Fed."
In his Paul Fest speech, along with those three words he said how it's a rigged game and mentioned banks loaning money at 0% and buying treasuries.
Whatever GJ may have said in the past about The Fed, he's on board the End the Fed train now.
Gary would need a miracle to actually win, so even if someone doesn't agree with certain policies of his, I don't think it's a dealbreaker at all. The main thing is to get a third party in the debates and to show the masses that a third party can indeed have a chance in future elections. At least at this time, I don't think an RP write-in would accomplish that.
If more people had supported a "Gary Johnson" in 1984, Ron Paul might have had a chance in 1988.
