They should probably give up on New Hampshire. And (if I were them) Republicans should definitely not yet give up on Virginia -the best Mark Warner can hope for (against either Davis or Gilmore) is a 55 to 45 victory, given the residual conservatism of the state. More likely he would win a percentage just slightly short of that.
So no chance whatsoever of Warner having a Bayh-style Indiana (a somewhat more conservative and Republican state) margin of victory? Of course, Bayh's Senate opponents were somewhat bottom-drawer. Neither Davis or Gilmore fit that description
