Marco Rubio may or may not still aspire to be president; I’m really not sure. If he does, he will have to juggle his responsibility to be Trump’s pro-establishment foreign policy good cop with his need to build bridges to the far right. It’s a tough job.
As a result, we see episodes like the one we had last week, when he allegedly told GOP senators privately that the very pro-Putin Trump peace plan wasn’t really an American plan, while he insisted in public that it was.
This won’t end well for him unless he has political skills we haven’t seen yet.
