He can always deflect it onto the GOP establishment.
He's going to need to put a face on it.
That's the whole point of the President: putting a face on the federal government. Having one, singular person the mob can point to and shout, "He failed me! He did the wrong thing! He's the one at fault!" That's the job Trump unwittingly signed up for.
He can try to deflect onto groups, but it's a soft deflection. The only way a President has honestly ever managed to deflect successfully is with a full-on boogeyman (communism/Russia, Osama Bin Laden, etc.). He's going to have to manufacture himself an "enemy", and it's going to have to be one big enough that the question of, "Well, why don't you just do something about him/her?" isn't too easy to answer. (In other words, it can't just be the leader of a protest movement or Anita Sarkeesian or whoever disagrees with him but is on a scale far too small to be taken seriously in this regard.)
I mean, even Obama dealt with this. "Thanks, Obama!" isn't just a meme, it's a pretty accurate reflection of the way people treat the President of the US as an anthropomorphic avatar of all their problems.
