It depends on what you mean by "his side". If you mean the Republican party (which is not really "on his side"), then you're right, they are in the best position to fight him. And they will do so if they hear a groundswell from their constituents that "this is not us". I am cautiously optimistic that this may happen. The condemnation of a number of senators, and probably more importantly, a bunch of Christian organizations, is a good sign.
