So politicians get votes, for promising to ban gay marriages and/or as reward for doing it? In other words, representative democracy is working as designed. Right? How is this different from other politicians getting votes for supporting gay marriage? It seems to me the "political gain" argument boils down to something almost meta-political; or of satisfaction/boldness in your tribe "winning", or politicians falsely professing things they know voters want -- these apply to both sides. When I asked, I was looking for something like how voter ID laws are supposedly really written to suppress voters from the other party. Is there some way in which banning gay marriage would inherently strengthen Republicans over Democrats? (Going with this because it was presumably the grandparent's example.)
