Do you really need any more evidence of this than people getting shot and people/press generally being okay with it?
Democrats who push gun control at the cost of everything else -- such as the possibility of turning Texas blue -- are a big reason why the party lacks power to influence anything else.
It's First Pass the Post that causes that. We have maybe 30% is the population that wants guns highly restricted and a different 30% that wants abortions highly restricted. We have something like 52% that want Medicare4All. But we just seesaw between gun grabber and pussy grabber because those M4A aren't the majority of either party primary.
MMP means the person running on M4A gets ranked in the middle by everybody, which is enough for a seat.
