Well, I am pretty convinced GOP can hold 6 states that are neither tossup nor leaning GOP, but safe R and likely R (polling average) instead. Then they need just 1 more seat from all the rest. There is pretty good chance they can win 1 of these: "Ohio,North Dakota,Arizona,Missouri,Wisconsin, West Virginia,Nevada,Indiana,Montana." That shouldn't be such a difficult job. I mean of course they can eventually lose in every single state, but if that happens, if you can't pull out 1 of the states mentioned above(if I had to bet I'd bet on more but 1 would be enough), then you should rethink where all of that is going and consider changing your job. I'm not even counting states like Virginia or Minnesota, and few more because I'm pretty sure they'll stay blue, even if they just lean blue.
