Does it really matter who stabbed you in the back at a crucial time. An unprincipled Repub or Dem who will face you and do it? Still dead though right
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.
