Ossoff raised 50 million, highest ever for a house race, and got clobbered in a winnable district. But Cruz is going to lose to a random Democrat in a deep red state.
Losing by fewer than four points in a district that's been Republican since 1978 is getting "clobbered"? Trump poached Price from GA-6
because of the district's safe-red status. It never should've been competitive for a Democrat. The result bodes very well for next year's elections in light red districts, swing districts, and light blue districts (some of which have Republican representatives).
Handel also got more dark PAC money than Ossoff.
As for Texas, I agree it'll be the most difficult of the three feasibly winnable races (AZ, NV, TX), but I wouldn't discount the possibility entirely. We have a good candidate, 2018 will be an anti-Republican year, and Texas has been getting bluer, if incrementally.
