Ron Paul doesn't have his own forum; Ron Paul is not the Liberty Caucus, he just uses the Alex Jones' radio program to spread his paranoid delusions. At that, I don't even think the national level of the Liberty Caucus has been very active lately, some threads are tagged, but I haven't seen much activity from them lately.
No, the closest thing we have to an official Ron Paul thread is the 'Friday Funny' thread where most people sit in shock and laugh at what he said.. that is pretty much what he is good for.
Did you really go and look at it? I just counted posts, and out the last 50, fully 41 are Ron Paul. Goes back to Nov 06, and most of the 10 earliest are not RP. I think RLC must mean Libertarian. Which would sort of explain it. Thanks. MF
