Libertarian Party -it is rather full of people who are not that much libertarian but are trying to get publicity.
Besides me you mean? I don't think there is one representative of libertarian ideology if you want a YouTube link or something like that. It is a fairly dispersed ideology, more so than others due to not being that mainstream and people arriving to it on their own. I do not think there is a good representative of left wing ideology either. That is why I would not give a link saying see left ideology crumble like you did. Because if a left wing person looses a debate that does not mean left ideology crumbles. Sadly I feel the kind of people mostly attracted to libertarianism are the kind who do not know how to "market" the ideology. They often preach to the coir and as if their conclusions are evident to others.
To give names, on economics Cafe Hayek is a good resource, for example.
