Not yet, but unless the GOP makes major changes it will be.
But are the sorts of things that have made Missouri more Republican the sorts of things that have lead to Virginia becoming more Democratic? In other words, would the correction in Virginia be detrimental to making Missouri even more red?
That is basically the problem the GOP faces. They have gone so far right to appease the base, they have turned off a ton of very important areas. To get these areas back, or at least make them competitive again the GOP needs to turn away from their base. The base isn't going to start voting Democratic again, but could start supporting hard line conservative third party candidates.
As an aside, how the hell are you still a Republican?
