I like your reasoning. But wait, doesn’t Hillary stand to gain and maybe much more than anybody?
I think Hillary thinks she benefits. If you look at the Republican primary as producing a wounded nominee with high negatives, then she may take it as an advantage.
Another way to look at it is the Republican nominee — assuming he wasn’t switched out by the GOPe — will have been tested in the crucible of the primary and will probably be more formidable in the general.
If Trump goes all they way — I’d like him to lock it up on the first ballot — then I think his experience with GOPe dirty tricks is a great proving ground for going up against Hillary.
