Absolutely correct. But Rs did have the votes to draft and modify bills in the Senate committee where there's no filibuster, and could have embedded pro 2A text in "must pass" bills. That wasn't done, not even once in 6 years.
Oh I agree with the overall sentiment 100%. Republicans spent the last two years acting like a group that didn't expect to win, found out they won and had no idea what to do with it and tried to throw something together overnight.
