I'd dare to claim that immigration, good economy (thanks, Obama!) and bombs here and there in ME would be pretty much enough for re-election and probably even for midterms.
What do you define as being enough for the midterm elections? Are we talking about minimal House losses
(maybe a dozen or so)? Personally, I believe his approval rating will still be the best metric for the GOP's midterm success. If Trump has high-30s/low-40s in October, then it's hard for me to see Republicans not getting hit with some sort of wave, even if only a small one. If Republicans performed relatively well even with an awful approval rating like Trump has now, that would probably be a historical record.
If those issues alone were enough, I'd like to think they would be reflected in his approvals.
