In one of the comments to this post, I was directed toward this website, specifically to its list of candidates who apparently believe in Paul-esque standards of liberty (I am not yet sure of the criteria to get on the list).
More on this as I know more about it.
In any case, if you are interested in continuing the fight that the Ron Paul for President campaign started, and in expanding it to Congressional races, then this is probably where to begin. Visit the site and get familiar with it.
That is all.
