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?
If the "correction" is based on getting back into the mid 40's in Fairfax and winning Loudoun/Prince William/Henrico, then yes it probably would be detrimental to the Missouri R coalition. On the other hand, an R resurgence in VA could be based on supercharged rural/Appalachian turnout and getting the rural areas to vote as R as the cities are D, which would also make Missouri even more R.
It's also worth noting that the focus on NOVA obscures just how much the Richmond suburbs have moved left and how much liberal turnout has improved in the Hampton Roads.
