The SSPX explicitly recognizes both the Pope and all Dogmas of the Church, including the Vatican I declaration regards Papal Infallibility.

Again, it does not matter. The decision was made years ago after a long discussion on a thread where your co-religionists - particularly those who post caucus articles - argued the points at length.

Those who want to have the Catholic Caucus include sedevacantists must use the term "Catholic/SSPX Caucus." And if they wish to include Orthodox as well, they must stipulate "Catholic/SSPX/Orthodox Caucus" or "Catholic/Orthodox Caucus" as the case may be.
