No, sorry, you haven't "got me the answer". The question is not whether candidates associate with an organization, it's whether the organization campaigns on behalf of the candidates.
You asked "Really?" and "Like where?" and my answers were "yes" and "at a minimum, FL, NV, NJ and NY". I don't have all the answers to the broader question you're now raising.
As for the BTP, as I was saying it's a branch of the Libertarian party. What does that have to do with the Tea Party movement???
As I already wrote, the goals and the name puts them at least superficially in the tea party movement. Maybe there's something deeper than that I missed in my 2 minutes on Wikipedia that sets them apart. It sounds like you think the former party affiliation of many (most?) of the BTP means they're not part of the tea party movement. Is that the point you're trying to make?
