Liberal Republicans in one county in Florida and another in Maryland who opposed the Christian right.
I think in both cases especially Charles County it was more likely due to suburban growth around DC as it was a more historically rural county and behaved accordingly until then. Although both of them saw Bush improving on Dole when it came to raw numbers, just not as much as Gore did from Clinton. Orange County is slightly more puzzling because it has been an urban county since Disney World opened but it's more likely that there were voters as you mentioned who focused mainly on taxes who opposed the Christian Right.
