There’s a good chance that the Democratic presidential candidate in 2020 will support gun safety measures like the public and the House do. As long as Republicans/NRA control the Senate, not much can be done at the federal level. At least the Trump administration banned bump stocks. It is obvious that no amount of mass shootings will change the objections to things like universal background checks and banning assault weapons. Too bad we’re not like New Zealand which banned assault weapons in about a week.
Our best chance for change is at the state/local level.
Republicans distort Democratic positions. Democrats are not going to repeal the second amendment and they’re not going to take your guns (with the possible exception of assault weapons).
