I’m not sure who you think stabbed you in the back nor when.
If you’re talking about the recent government shutdown, I wouldn’t call that a back stabbing. That shutdown had no chance of success and it’s just as well that it was ended before it caused any lasting harm to republicans.
The GOP wil not lose any seats b/c they put govt workers on paid vacation. LOL They could lose seats if they show their lack of principles. Farm bill pork enabling they just lack principles and shoot or stab any in the back who calls them out. Ask Sarah Palin or Ted Cruz for example. Cruz Lee and Rand Paul to lesser extent are heroes with not enough allies.
