Republicans will not lose the gun control debate. Just keep up the pressure on politicians who fake being conservative, like Tom Coburn, who, like a snarling dog straining at his leash, is already talking about expanding background checks. Yank their chains. If they are still snarling, pull on their chains until you strangle them.
While you are doing this, also keep your eye on the pathway to citizenship and the debt ceiling fights. If you don't watch Republicans every second in every issue, they will betray us.
