%       CQA.  The CQA lists nine different types of votes: voted for, paired
%       for, and announced for (these three simplified to yea), voted
%       against, paired against, and announced against (these three
%       simplified to nay), voted present, voted present to avoid conflict
%       of interest, and did not vote or otherwise make a position known
%       (these three simplified to an unknown disposition).
