I honestly believe the current SCOTUS will start hearing 2nd Amendment cases, and will rule according to the Constitution. Lawmakers are most likely well aware of this, and I will be surprised if significant new gun restrictions are passed. Politicians know that once SCOTUS rules, they have given the final answer. Passing anything dramatic at this point in time could very well lead to the type of ruling that ends many of the left's favorite pastimes (ex. purchase limits, magazine capacity limits, Assault Weapon bans, etc.). I'm not saying there are not people in Congress who are dumb or delusional enough to try, but I think they will meet serious resistance from senior lawmakers who paid attention in Civics Class.
