Schumer was dragged in to this one by the last shooting, (Heaven forfend that they admit a law abiding NRA member and NRA instructor ended his rampage with a lawfully owned AR15!), but he, the little slime devil, knows that "gun control", also known as unilateral personal disarmament, is a serious non starter. They make the stink now, instead of at election time, and avoid the backlash that always comes with such an attempt. This way they can face the faithful and say, see? We tried!
Having said all that, there is nothing so dangerous to liberty as a scared politician, and many Republicans are running scared from the President Who Will Not Be Controlled, and capable of making stupid career ending moves, so yes, contact your elected Congress critters, and le them know you oppose this completely and utterly.
