The last time I read the CP platform, it didn't say anything about prostitution. Their stance on drug use is that the federal drug war is unconstitutional, and the issue should reside with the states or with the people. Their position on gambling is that the government shouldn't promote gambling through state lotteries or state owned casionos. That's a libertarian position.
"Goode is an advocate of a federal prohibition of online poker. In 2006, he cosponsored H.R. 4777, the Internet Gambling Prohibition Act.[23]"
Nothing Libertarian or Paulian about that. Gary Johnson on the other hand has taken a strong, correct position on the issue.
Johnson is 90% the same as Paul on the issues. Goode is maybe 65%. He was a Democrat for most of his time in office.
