Read the ALPA C&BL's and you'll find the answer.
Hint: Local Representation. As usual, our officers of 77 still haven't held the required LEC meeting per the C&BL's, due months ago. They are the official forums of discussion and interaction between the membership and officers. They can't even manage to hold required meetings (again). It's simply time for DFW pilots to elect their own local reps and conduct our own LOCAL business. All LAS based 77 officers might think that's not important. We beg to disagree.
By the way...PUB events are not meetings where resolutions and official business can be conducted.
Remember the IAH unity event when JA introduced himself as the "Las Vegas FO rep"? We all immediately stared at him and RP caught it a couple of seconds later, jumped up and said "and DFW too."
Want another reason?
