I wish I agreed with your optomism here but I dont. This has become too big an issue to let it die in committee. Some version of it will get brought to a vote. If its a watered down version and is not fiercely opposed it will likely pass. I think they probably have enough votes now to pass universal background checks and probably mag capacity limits. Do not be overconfident here - Act and oppose it.
