Make a donation, sign a petition or make any contact with a group and you will get listed as a "member". Usually the membership "list" is just a number used for lobbying purposes and little more than a mailing list.Vets like myself do not join groups...Well that sounds like a reasonable excuse to ignore 400,000 veterans.Yawn.....
VoteVets.org is organized as a non-partisan political action committee (PAC) ... "closely aligned with Congressional Democrats," and "liberal" in news stories.
It says they have 20,000 members, I doubt the other 380,000 agree with them
