Gee, I feel like I've seen this discussion around here once or twice before. Same tired arguments.
In a nutshell, this is another of the "if you don't think like I do, you are a _______" topics.
Let's drum up some fear of the other guys. They are coming for our guns. Obama, Schumer, and Pelosi will ban them all! Except they didn't do anything when they had control.
Our team is pro-gun! When we have the house, Senate, and President watch out! Except they wouldn't even vote on a pro-gun bill. Not even something like taking suppressors off of the NFA list or national reciprocity.
And I will say again, those you call RINOs, are the Republicans. They may not be what YOU think a Republican is, but they are what the Party is today. They are probably CINOs.
While agreeing with the sentiment of your post, the the Dems did not do it because they thought they were in charge and had time. Just like RBG did not retire because she wasn't ready and it was assured H would win. They also liked fund raising off of it. Side note, if she has to retire before a Dem is elected they will go nuts. This is currently evidenced by the inability of Dems to even condemn anti-semitism, if a Repub had said similar a majority would be all over TV preening as they blasted the individual.
The Repubs on the other hand are more truly diverse in thinking and if you think they were on the same team you were not paying attention. Then to make things worse, every time it was being reported that a pro-gun vote was coming, a new major shooting occurred right before. It was uncanny how coincidental it was. Then the moderate Repubs got all wishy-washy...
Not defending, but rather pointing out how it went down.
