Surely the place to raise this first is with the members of both clubs. It is they who should express their views to their committees and it is then for the Chairmen and committees to implement the majority view of their members.
To do that of course, you need committees who are committed to a merger, and when I was involved with the Enthusiasts Club as Secretary and Chairman over a number of years, that certainly wasn't the case. In fact we considered it on numerous occasions and rejected theidea, just like the GTD committee have.
There are democratic mechanisms for raising this issue within the clubs, not least by raising it with the Committee or asking for it to be a discussion item at the AGM.
In my opinion, a poll such as this, which does not distinquish between the views of members, and those of Non members ( who might be potential members) is useless.
